Repetitive... Needs more to be a bit original.
There was something awfully familiar about this game when I played it. Lo and behold, it seemed to be a rip of a popular game... just with a different theme.
Had I not known this, I probably would have given it a higher rating. The original creators of said script get my thanks for making it easy control the cursor for aiming. While the idea behind this particular game was interesting (I'm actually pretty fond of MegaMan, but for some reason, it amused me for a bit), I think some originality is heavily needed. It gets pretty boring shooting all the MMs after a while... Probably add some bosses? Other characters? ... Some music, maybe? We need at least SOME incentive to keep on shooting them. =P
Anyway, good luck with your progress. I hope to see some improvement once updated.
