There are some really good ideas here, I like how the actions you take can change the walkable areas of the level. I found the levels a bit too challenging, I think at one point I got stuck and wasn't sure how to continue, however at that point I might have not understood all the game mechanics yet.
The overall game feel was one of exploration, but you could also go the route of something darker if part of the purpose is not to get stuck, like some dark music leading up to danger or some other darker theme elements for your self-inflicted entrapment.
