super cool way you made the game look and feel, beautiful sprites and nice matching sound to the game vibe. I though feel it takes to long to kill a enemy, its quite a few attacks you need to go through in order to kill the enemies, when you start the game. I would think it should be sorta faster to kill the first few to get the player hooked. Nevertheless i think you got something really cool going on here, and with some more adjustments to the gameplay this could actually be a even cooler game :D
Good job ma dude!
