Very relaxing haha.
I don't know if it was intentional, but I liked how the rewind on death mechanic helped you overcome the last place you died on, in order to help you eventually reach the end. It was clearly not the main focus of the game, but it fit the game well.
The rocks are a bit weird, it's kind of hard to see how far they are. I ended up dying once or twice because of the weird depth perception, thinking a rock was far away when in reality it was right on top of me. But the rewind mechanic (and the stamina dash, too) helps counteract this a bit. And the second level is too easy, I never needed to rewind at all!
Good job!
