The game was great and addicting, but there were three problems:
1. The laser disintegration animation was the same as the enemy disintegration, making it look like the laser got goo allover you
2. The first and second boss were almost the same, just no doors the second time, mix it up a little, like a flying boss or something.
3.Wall jumping was such a pain in the ass, it wasn't responsive so I would say that even if your 2 pixels from the wall you should be able to jump, this would make it easier.
