I enjoyed the game how ever the level progression is fast and random for I had trouble with some levels then the next level I had no problem with. I would also try to fix the collision with the platforms for I kept getting stuck in the corners. I also don't know if it was planned to do wall jumps but on some platforms you can while others you can't. I would make the walls green to show you can wall jump on it. I would also make the enemies red for if you add moving platforms it will be difficult to tell platform from alien. this was on the 1.01v.
