I like the simple black and white aesthetic for the levels and the character, especially how it contrasts the present mode vs past ghost mode. I accidentally solved the first level by just fooling around. It's hard for me to distinguish what is in the environment and therefore hard for me to solve the puzzle. I wasn't able to get through the second level either, and I found the pit with water at the beginning to be a bit annoying because there were no indicators that it was there + it didn't help me utilize the time rewind.
Overall I think the rewind time mechanic is pretty creative and executed well visually, but the levels could use some tweaking to make at least the first few puzzles simple to solve. I wish I could explore more of this game but I got skill issued.
