The art is fantastic, especially the character talking animations, they have a lot of personality. I like the attention to details like the rewind sound/animation and the character sprites moving as well as the portraits when talking. Gameplay wise it's very easy and didn't really need me to actually think about the solutions to the puzzles until maybe the last screen. It would have been nice to continue and have harder puzzles that explore the moving turret mechanic more.
I think there is a bug where rewinding after a death changes the bullet patterns, you can abuse this to bypass turret sections.
