I also like this game a lot and agree with whak Vizipokemon said: At the beginning it is not clear what is expected. And there should not be a fall back to level one. After all, it is a well made puzzle game, the theme feels like just put on top of it and does not help to make the game more interesting. So I suggest to keep on polishing the game after the jam and just get rid of the treasure hunt where you are not allowed to get the treasure.
Having said that: from a philosophical perspective you did it very well, winning is easy, but loosing is the actual fun. In this way: perfect for this jam :-)
