Cool music and cute characters! Good Job ~
It's a really cool game.....if it's your first LD. Please ignore the followning comment if you don't want to see critism.
It seems the graphics and music got highly focused. They are cool, obvirously, but not in a comfortable way. The sound effect is cool, but it does little on helping the player to distinguish different damge effect. The characters are cool, but they are always the same, while their level changed. A simple change in scale or color can help to point out the difference between different levels. The sacrifice mechanism - which is cool - become totally useless because of the urgent gameplay and the hard-to-click upgrade buttons. I cannot handle leveling up and killing elements in the same time. Maybe a waiting phase can be added?
A really good try to make your own music though.
