The soulsucker's 50% chance of coming back gets ridiculous, one kept coming back throughout the ENTIRE level, even after the level was over it just wouldn't die. But the rest of the game is great, 5/5.
Ok, I read all the comments and decided to give the game a try anyways. As I went along I discovered they were right, the game's concept is awesome, but there are too many little problems for this to actually be a good game. I tried to make a list to type in a comment, but there are too many, if someone manages to fix all of those, this would be an amazing game. 3/5
