Spaceship Color is a colour-matching reaction game in three dimensions. Your ship flies forward down a corridor of gates, each a different colour, and you can only pass safely through the one that matches your current colour — which changes as you go.
It's simple to describe and surprisingly demanding at speed, because you have to read two things at once: which colour you are, and which gate matches. Runs are short, restarts are instant, and the score is distance.
Steer your ship through the gate whose colour matches your ship's current colour. Passing through any other colour ends the run.
No — it's an endless runner that accelerates. Distance is the score.
Yes — drag to steer. It runs in any browser with nothing to install.
