Wait... You can't be serious... We're going on with the Mars mission?! Am I the only one concerned with the hundreds of flying saucers hovering just a few miles over the Earth?!
Nice game. Really challenging. Some sound effect might help polish it up. Having to press space after dying is kind of annoying, especially since you die so much. Maybe a very short animation placing you back at the start. I would also like to see some transitional animations when shifting gravity, i.e. actually animating your character flipping over, rather than just popping from one to the next. Good game overall, though. 4/5
I'm sorry I have to say this but this game is terrible. I would have given it a 0 if it was an option. If you are going to make a game, at least spend more than 10 minutes on it.
