I see another individual went with burning stuff as their theme!
Love the idea, fire spirit running from the rain-spirits, very cosy and fun idea, however not very replayable, if you ever return to this I recommend rewarding faster completions of days, and making subsequent days more difficult. More enemy variety could be fun! Maybe big water spirits could show up that take away 2 or 3 heat at a time but move slower? Or ranged dewdrop spirits that shoot water drops at you.
Just shooting ideas your way that could make a cosy fun game more replayable since I don't see any reason to return to this after playing it once.
