Genesis is a decent game. The beginning is fun enough but remains rather annoying in the fact that you have to constantly keep space pressed to be making real progress. This isn't really helped by having to also hold enter in a number of places to properly buy things. The game gets decent when you hit stars and good even by the time you can let go of space, but the Reactor has it's own issues that made me use it as sparingly as possible. The Reactor also could've benefited from being able to choose how much to make instead of forcing you to use all of your oxygen in one go. Overall it was a fine, original experience.
