Amazing! The controls were great and I loved the puzzles you made with the mechanic! There was a lot of depth to it and I think it'd be interesting to explore the idea further into a full game!
One thing is I don't think the choice to map controls to shift and ctrl was good, I was using all five fingers of my left hand and none of my right, it also made it difficult to dash and rewind. Maybe in the future map them to different keyboard keys.
I loved the art you made! Great game!
