I like what you've done here with the rewind mechanic. This is a polished game in many ways- the lightning is nice, the player moves smoothly, and the physics engine is decent. I like this concept though and I love how the graphics look and the surreal vibes from the Limbo-esque background. There are a few issues, but nothing too bad- as others have said, the rewind is too slow. I also found pushing boxes too slow as well. The jump pads had some janky physics- I had a hard time at the level where you have to use it to get across a big gap; fall speeds are a little weird too. I also got softlocked at one of the parts where you have to use a box to get out of a hole- I accidentally pushed the box into the left wall. Overall, I love the vibes and ambiance you've created with this game and I believe you can easily improve this game by making just a few changes. If it's not too much trouble, I'd really love to see a review on our game, if you have the time!
