What an interesting game! The puzzles were challenging, I liked the 3D models for most of things. I didn't realize you could run at first, but that made some puzzles way easier.
One thing that I didn't quite like was that when rewinding your view also rewinds, which makes sense, but in level 4 I believe, the one where there's a lava pit and moving platforms, it felt quite uncomfortable, since I had to rewind to reach the moving platform but I didn't know where it was at the moment. Maybe being able to control the view when rewinding could be good, but I'm not sure.
Despite that, it was a great game!
