Buggy
Buggy game. Levels do not end (other than A), even after playing for over 30 minutes (just see what will happen). Tried to kill myself only to find out that I couldn't die, I had became invincible, unable to ever leave the level. Those bugs marred a perfectly good side-scroller. Fix those and you will have an acceptable game. (excellent programming effort here, great tracking of homing shots!)
