Every game has a "Needs Improvements" review and today i'm making yours.
First: Great Game and very fun and addicting
Second: Levels need check points because I'm tried of having to kill everyone over again because i made a mistake on the final guy
Third: Needs more levels.
Fourth: I didn't beat the game but if there isn't any you should add blocks that go left, right and up.
Fifth: Everyone is complaining about the difficultly so i suggest to fix that.
Sixth: You should add different bad guys who are smarter or bigger then the regular diseased.
Fix these problems and you game will get a better score*
