Great game so far! I like the idea of swapping to another creature if you get caught. I'm not sure I entirely like the time limit, I want to explore more and there's no indicator to tell you how much time you have left.
It seems like this could be a good puzzle game, trying to figure out how to get to the next safe circle with stealth and deciding where to get caught to possess a better target and using the crystal to bust through if those options don't work.
Perhaps the crystal (or completely separate items) could have more effects? "eating" one gives you more time, being caught with one allows you to choose your next possession target, or hitting an enemy makes them want to catch another target.
Two bugs I found:
- Touching a non-frozen enemy as a werewolf makes your character completely disappear (no wisp)
- The player can't always make the screen transfer to the end of the level. Are there multiple potential entrances to the end? I could only find one.
