I love:
- The graphics
- The overall mood cold and soft at the same time
- The camera movements dampening (though in some edge cases it's too slow)
I would have love if:
- Laser buttons (big white squares on the walls) were introduced more explicitely. I spent 3 minutes going everywhere in the first level using a button with the annoying laser tower following you and trying to push you in the huge pit with an elevator.
- There was more challenge (not necessarily more difficulty). Most levels I just spam clicked my way through without really thinking where to go or how.
