Loved the 2D environment. The 3D part may have further use if you decide to continue with this game. But as it stands, i can't see much relevance to it other than giving the narrative an aspect of dimensional travel. Maybe have a static image instead of freeroam if the use of the room is that limited. You probably spent time you didn't have developing that part.
The graphics are nice, the aesthetic is consistent, the music and the mechanics were doing what they were intended for and come together nicely.
I do not know what the function "bend" was for? i tried to use it but i don't think it worked.
