Not good at all.
It wasent thought up well, and it aint a original idea. ALSO, you didnt put in any audio or REAL game play. To say the worst, it basicly was a waste of 5 minutes. Srry, but dis wont pass the grade. MABEY, if you improved the graphics, put some music in there, it might make it. You need more work, and I bet you can do it. IT was a good consept, but you didnt deliver on the game play. Ill give you a 2 out of ten because it has the halo background. I LOOOOVE hALO!
