This game has very little to do with its title.
A Game Development Project! With music! And a seal!
todo: more description? I don't have much to say about the game. Perhaps a more knowledgeable person (cough-@butterseal-cough) may chime in.
Butterseal is the name of the puzzle-based RPG herein. The basic idea is literally saving the world through music. Music brings warmth, and this is what thaws a silent, frozen world. Throughout the game, you acquire certain spring-related powers (to combat the theme of winter). These powers help you through subsequent levels, and culminate in the final boss level against a secret imposter.
Oh, and puns.
Lots of puns.
