Hi, I attempted to play this game and ran into a few issues that made progressing impossible.
First, if you decide not to purify the snowman, you cannot continue. You have to restart the game in order to purify it.
Second, if you do purify the snowman, eventually, img/animations/StateDown1.png will fail to load, and you cannot continue the fight.
This looks like it has a lot of potential and I am excited to play, but I literally cannot progress. If you can fix it, that'd be wonderful! If not, it was still interesting to play as far as I got. Thanks for putting the time in to make the game!
