Ultimate Assassin 2 It's like Metal Gear meets the Classroom!
I am a big fan of stealth games. For how fun this was, I think in the next installment (if you're planning on one) you could use a bit more variety. Maybe... I dunno, red guys who just stands guard there, or a yellow guy who runs everywhere... Or vents! Anyway, I enjoyed this for about an hour, and I'll give you an 8!
