I enjoyed my time with loop roll. I thought the puzzles were enjoyable. The last one that involved sending the ball back up to be hit again was a great surprise. The ball rolling sound effect also made playing the game very satisfying. I really love the idea of having those key frames loop because there are so many puzzles you could create with that, epically when you have puzzles that require many loops of the keyframe to get the ball back to square one. I would love to see the idea expanded upon in more levels.
