Fun game with good comedic elements, I had a good time :) I noticed some of the other comments said the graphics weren't good, I actually didn't mind at all. I like the art and I think it fits the tone of the game pretty well. :)
The levels got too hard for me after a while and I didn't get to make it all the way to the end. One of the problems I had was not being able to see the moon side from the Earth or vice versa. I'm terrible with memory when it comes to platformers so maybe something to help with that would have been nice.
The sound effects and music were a good fit for the game too. Just those two things alone conveyed the comedic side of the game really well. Good work!
