i dunno. but with the skill- and nerve-wracking button-bashing, this game provides both fun AND annoyance. definitely not for those without skills and intuits (read: complainers). for a flash game, the game's not quite good into it's sprites, but the game definitely makes it up with the backgrounds. ye. castlevania and metroid it is! =D
judging from the others who have commented quite on the downside, i guess there's room for improvement on the score submission, among other design factor like points multiplier. otherwise, it's a good puzzle game with plenty of space for intuitive playing (what i did was get the logic of the game WITHOUT looking at "how to play"). one comment is right: this might go up with tetris as a classic stacker game.
3 days, kinda easy
machinegun for a last weapon. but the m16 is better than it.
simply sweep the incoming enemies and heal the balloon while they're not coming in
