The game's either too hard or too easy with no inbetween, and it revolves around how weak Stanley's main bugsprayer is vs how strong the Super Sprayer is. In addition, if you beat a previous level with the Super Spray active, it won't appear in the next level until you die. There's also a bug where the super spray you have carries over into the next stage so you can clear it in seconds.

Who is Stanley and why does Donkey Kong want to ruin his day so badly anyways? Why do the bugs hate him so much that they will destroy his corpse the moment he dies?
