well............
it was good for a first game, but way to fast
you should either make the objects way smaller, or make the room size much bigger, i reccomend either as, if the enemy was coming towards me, i would go into super engage mode and kill him, only to exit it and smash into the new enemy behind him that just apeared
a boss would be cool, a bunch of reds formed together to make a man, and "greens" that take two hits or even "blacks that take 3 hits
good job..............sort of
