I like the game. But, I feel like the difference between the astronaut and the other sprites is kind of annoying, For a game to look neat, you should use everything from the same pack, or make your own.(I know there probably wasn't an astronaut in the same pack you got the yack from, so that would probably make sense for that). Also, I feel like some background music would make this game feel less empty. Also, I thought it was weird that I could walk through the fence.
Anyway, it was still enjoyable.
