Poom

Imagine Doom. Now squeeze it into a screen the size of 128×128 pixels, limit the palette to sixteen colors and give the creator just a few kilobytes of code. It sounds like an impossible brief — and that is precisely why Poom is one of the most admired pieces ever created on the PICO-8 fantasy console. It is a full-fledged first-person shooter in the style of classic id Software that runs where no one would expect it.

PICO-8 is a so-called fantasy console — a virtual machine from Lexaloffle that deliberately mimics the strict limitations of the eight-bit era. The programmer has only a handful of colors, a tiny resolution and hard limits on program size at their disposal. It is precisely within these boundaries that the magic of community creation is born: every project is a bit of a contest with its own platform. Poom wins this contest with ease, because it proves that even pseudo-3D rendering with textured corridors fits into such a small box.

In terms of gameplay, Poom relies on the tried-and-true DNA of the genre: you move through a maze of corridors and rooms, collect weapons, look for keys and eliminate enemies before they eliminate you. The pace is brisk, the controls straightforward, and the whole thing has just the right dose of old-fashioned brutality, where it is not about cover and regeneration but about constant movement, mapping your surroundings and collecting medkits. For fans of nineties shooters it is like a handshake with an old friend.

The cultural significance of such projects goes beyond the gameplay itself. They show that creativity flourishes within constraints, not in spite of them. Where today's developer has practically unlimited power at their disposal, the creator for PICO-8 must weigh every pixel and every line of code. The result is a purity of design that big-budget titles often lack. In this respect Poom is a flagship demonstration of what it means to make a lot out of a little.

Because this is a community homebrew title, I will not pretend to know exact sales figures or awards — fantasy consoles live more in shared cartridges and the enthusiasm of authors than in charts. What matters is that Poom is freely available, playable in the browser and on devices that can handle PICO-8, and serves as a calling card for the entire scene. It is a small technical miracle worth a few minutes of your time.

Why play: A Doom-like FPS crammed into 128×128 pixels of PICO-8 is a technical tour de force and a snappy retro shooter in one — proof that constraints give rise to the purest design.
