Such an interesting concept. I loved how the game occurs in two different "planes". I didn't understand a few things, but I believe that didn't detract from the experience. The sprite work was rough but charming. Some of the rooms were absolutely stunning - specially the ones in the forest with all of the foliage. If you end up doing and update, please consider adding a looping track. I think it could enhance the experience.
I'm super glad you participated in the jam! This was good.
