Enjoyment: Overall I had a great time. There were only 3 small details i noticed, which annoyed me a bit. First off, would loved an additional input/button to reset the second part of each level, as Q reset back to creating the movement pattern part. Second I'd like it better, if the recorded path would already be displayed right after the first repetition, maybe this is a bug/unintended that it takes an additional try to reveal it. Third, most certainly was a bug, after pressing the reset stage button (q), sometimes it would reset a second time without input - was maybe the wrong input signal connected to ?
Gameplay: Easy controls - although I always prefer a separate button to the arrows for jumping. Got stuck quite a bit in the playthrough between platforms, no big deal to the reset scene function. Dunno if it was intended to have the forces of the self-controlled platforms, it was funny to shoot the main character through the roof.
Innovation: That was refreshing - classic platformer with an exciting twist to it. Furthermore I can imagine you can iterate upon this new mechanic further. Top category for my review.
Theme: Even without the main character I would have bought the implementation of the theme as a stage play, as the stage can be mysterious magical and strange of course.... Mechanically speaking I thought the moving the platform in the rear view playthrough partly also presses towards the theme. well done.
Visuals: While not my personal favorite, you've done a great job at having a consistent art style that also helped give the polish feeling - well done in the visuals department
Audio: I like the background tune, its very supporting the gameplay in mind and I love the sfx queues from time to time, subtle but strong - very good job in the audio department.
