The Crimson Diamond

For about thirty years, the text parser has been the adventure genre’s embarrassing relative. Sierra dropped it early in the 1990s in favor of icon bars, point-and-click took over, and the reason was fair. Typing LOOK AT DESK and getting back “I don’t understand that” was never fun. Too often, the parser turned a detective story into a guessing game about vocabulary.

The Crimson Diamond argues that the parser was never the real problem. The design around it was. The only name on the Steam developer credit is Julia Minamata, and the game is built like one person’s project. It is drawn entirely in the 16-color EGA palette and borrows its structure openly from Sierra’s The Colonel’s Bequest. You play Nancy Maple, a junior clerk and amateur geologist at Toronto’s Royal Canadian Museum. Her job sounds routine: go to the nearly abandoned mining town of Crimson, Ontario, and check out reports of an enormous diamond. When she gets to Crimson Lodge, it’s already full of guests who all seem to be hiding something. Soon the mineral survey becomes a murder investigation.

The game belongs to the wider retro-adventure revival, but it reaches further back than most of that crowd. Many modern adventure games use pixel art while keeping modern point-and-click controls. This one brings back the thing players were happiest to lose, typed commands, and bets that careful design can make them enjoyable again. It’s a niche bet, and the game doesn’t pretend otherwise.

The reception suggests the niche is bigger than expected. The game holds an 88 on Metacritic, which is notable because parser games tend to lose players the first time they’re asked to type. This one mostly keeps them, and the reason is worth looking at closely.

• Parser plus notebook: Typed commands handle examining, taking and questioning. An in-game notebook records your findings and also works as a hint system and a list of accepted verbs.
• Hybrid control scheme: You walk by clicking and type only when you want to act. You never type GO NORTH.
• No combat, no unfair deaths: The sudden, sometimes unfair deaths Sierra was known for are gone. Getting stuck is the only real failure state.
• Deduction by observation: You make progress by eavesdropping, searching rooms while their occupants are away, and piecing together timelines.
• Endings based on evidence: Several endings reflect how much evidence you actually collected, so a thorough investigation gets a better result.
• Geology as a mechanic: Nancy takes rock samples, which keeps her day job part of the play rather than just a detail in her backstory.
• Period presentation: Hand-drawn EGA art, a chiptune-style score in the spirit of the era, and 26 Steam achievements across a campaign of roughly 8 to 12 hours.

The Parser, Rehabilitated

The notebook is the single most important decision in the game, and it’s a smart one. Classic parsers failed because they gave you an unlimited input box with a small hidden vocabulary behind it. You spent your time guessing the designer’s words instead of thinking about the case. By listing the verbs the game accepts, the notebook turns an open-ended guessing game into a vocabulary you can look up.

That cuts the onboarding friction that sank the genre. The question “which word does it want?” gives way to “what should I investigate next?”, which is the right question for a mystery. Clicking to move helps too. Typing is reserved for moments that matter, so each command reads as a decision rather than routine navigation.

The fix isn’t complete. A few puzzle solutions are obscure or need precise phrasing. A verb list tells you that TAKE works. It doesn’t always tell you which object, in which form, the game expects in a specific moment. When that breaks down, the old Sierra frustration comes straight back. It’s rare, but a parser game is only as good as its worst failed input, and newcomers to the genre will hit a few.

The Investigation Loop

The core loop has a clear rhythm. You explore the lodge, examine everything, listen in on conversations, slip into rooms while their owners are elsewhere, question the guests, and write down what you learn. Then you do it again with better questions. This is The Colonel’s Bequest’s DNA: the house feels lived in because its residents aren’t props waiting for you to click on them.

That design rewards paying attention more than combining inventory items, and that’s the correct choice for a whodunit. The satisfying moments come from noticing that someone’s account doesn’t match where they were. They don’t come from rubbing an odd object on another odd object. Rebuilding timelines makes you think like an investigator.

The cast carries a lot of weight, and it holds up. The guests are written as warm and eccentric, and the Canadian setting and cozy-mystery tone are among the game’s clearest strengths. So is the sheer amount of optional detail to examine, which is the parser’s natural strength. A point-and-click hotspot has to be placed on purpose. A parser can react to anything the writer thought you might try, and here the writer thought of a lot.

The geology deserves its own mention. Taking rock samples keeps Nancy’s job part of the play, and it separates her from the generic amateur sleuth. It’s a small touch, but it gives the character a real reason to be poking around.

Friction by Design, and Friction by Accident

Apart from the notebook, the biggest modernization is removing unfair death. Sierra games were known for killing you without warning, which pushed players into constant defensive saving. With that gone, you can explore without worrying, and exploring is the whole game.

Not all the friction is intentional. The opening act is slow. It spends a long time on setup before the plot really gets going. The lodge, the guests and Nancy’s reason for being there all need establishing before the stakes land, and the design honors that need. Still, a genre with a reputation for being hard to get into can’t afford a sluggish first hour. A tighter opening would have served newcomers better.

Endings That Grade Your Work

The multiple endings are the smartest structural choice. The game measures how thorough you were instead of blocking progress until you’ve found everything. You can reach a conclusion without every clue, but the ending reflects what you missed. That’s much better than the old hard gate where one missed item stopped the game for good.

It also gives the 8-to-12-hour runtime a reason to be replayed. The 26 achievements push in the same direction, toward completeness. A second run with a better idea of what to look for is a different experience, and the game is designed to support one.

Sixteen colors is a hard limit, and The Crimson Diamond uses it deliberately. The artwork is hand-drawn inside the palette’s limits, not modern pixel art run through a retro filter, and the difference shows. The format’s hard color edges and bold contrasts give the lodge and its surroundings a clear, graphic look. It reads like a real Sierra box screenshot rather than an imitation of one.

The same goes for the chiptune-style score, which suits the period. Both choices divide people. The visuals and music are an acquired taste, and that’s fair. If harsh EGA color and bleepy synth music don’t appeal to you, the game won’t change your mind. For its intended audience, the look is a big part of the appeal.

The interface is plain in a good way. The text entry line and the notebook are functional, easy to read and out of the way. Hardware isn’t a practical concern: a 16-color adventure game of this scope is light on any machine that can run Steam.

On Steam, this is a mouse-and-keyboard game first and last. The control scheme works best with one hand on the mouse for movement and both hands ready to type. On a desktop or laptop it feels natural.

Controllers and handheld PCs are a harder fit. Typed commands are central to the design, so on a device without a physical keyboard, every EXAMINE or TAKE means opening an on-screen keyboard. That adds delay to the very action the game is built around. For couch play, pair a real keyboard.

The Steam storefront helps the game in a less obvious way. The 26 achievements give some structure to a genre that usually offers little sense of progress. Achievements that reward careful investigation also hint at what you may have missed, working almost like a second hint layer on top of the notebook.

The Crimson Diamond does more than recreate a dead interface out of nostalgia. It finds what broke the text parser, a hidden vocabulary and unfair punishment, and fixes both with a notebook and a no-death policy. What’s left is the parser’s real strength: a world that responds to your curiosity, set inside a well-built whodunit with a cast worth questioning twice.

It isn’t flawless. The first act drags, and a few puzzles still expect you to guess the designer’s exact wording. Those problems are real, but they’re the exceptions. Julia Minamata has built a strong case that typing can still be a satisfying way to play, and we recommend it to anyone even slightly curious about the parser era.
