My first attempt into the game was fine, but trying to get into the other levels, from the level selection, confused me. I realized I had to wait for the musical cue to finish, before it took me in, so I think it would be good if that was more clear. Perhaps a simple loading screen or something. I thought I was dealing with a bug.
Level 11 in particular, I don't think was possible to solve. It required you to put the owl girl's totems in the "totem slot," but there's only 2 of her and her totem is levitated.
I think to help the game, it should be less of a puzzle game and more platformer like some of the first Mario games.
