The puzzles are really fun. But the camera was frustrating.
I had to leave the camera in "Free move" because it was the easier to focus on the puzzle.
The rotation motion with the center position moving wasn't helpful. I had to constantly re-adjust the camera to concentrate on the puzzle.
But everything else about it was great. I really love the walls opening up and wind particle effects. And the mechanic itself it simple but incredibly challenging.
And I wouldn't scrap the 45 degree rotation. I found it very useful in examining the play space which gave me a sense of control that I wouldn't have otherwise. I hope that's helpful.
Either way, nice work! Would love to see more to this!
