I've been working on a game Hello Triangle for a while. In the game, you build a GPU one part at a time by wiring circuits, and renders a picture on the screen with what your circuit computes. I have a free demo available that goes up to drawing a triangle, while I'm still working on the rest of the game.

You don't start from logic gates. The game starts with adders and comparators. Every wire just carries a fixed point number, and there are no bit widths to think about. The reason of using fixed point numbers is that veteran players of Turing Complete can skip the bits part they already player, while players who are new to programming can still jump right in.

The circuit simulator is written in Go and the game UI is written in Godot, and they communitate through stdio. I also built a score server that players can upload their scores and compare with each other through score histograms.

The demo is available on Steam (Windows/macOS/Linux), there's also an itch.io build if you don't use Steam. Curious what you think, and where you get stuck!
