3/5. And because I refuse to add a pointless, "This game sucks" or something better, I'll tell why. While it is challenging, it doesn't seem well constructed. There's a bit of an adrenaline rush to it, but a mistaken mouse can end you in 2 seconds.
Besides this being perfectly made, it's incredibly addicting. It's fun. The levels are well divided, but not hard to go from one to the other. Some songs are just crazy, others are relaxing. 5/5
The game is genius. Precision, planning, and skills seem constantly necessary. It keeps you on your toes. The only reason I gave it 4/5 instead of a 5/5 was because I graded it a tad too quickly.
I went with a 2/5, because this game can be very repetitive, the balance on weapons can be harsh, and the AI is rather... bad. However, it is addicting, at least for me.
