Beam Racer

a platformer inside a CRT where the electron beam is part of the level, very nerdy in the best way. short and rough like you said, but one of the more original ideas i've seen here

Great concept and a clever way to integrate old tech into a platformer! The slowdown mechanic is cool, and the reflection is a nice addition. Short but sweet!

I think there is an issue with procedural/random generation of platforms, which I encountered couple of times, when the next platform spawn too high for you.
