Great game! i can see people have already addressed the issue with the unknown ending, so i won't talk about that. I like it, and really like the idea of different abilities in different... dimensions? Anyway, that's something i haven't seen before. I also like the room design(i'm talking about the visual, not the functional). In the end, i got a little confused about the different rooms, because i had some problems knowing what room to go to, so i just spammed the shift key, until i found something interesting.
But great game, i like it a lot!
