Dude I like this. It's fun, I love the background music and the concept. I like that you added a pause button, a menu button and a try again button. I think those are always essential and a lot of people forget to add them. Nice that you made all the assets yourself for the jam!
This could make for some interesting puzzles, the ones in the game right now are quite easy and the game is short.
I was actually drawn to the game because you used "rewind" as the act of re-winding toys like I did ;) Although, in this game you aren't really rewinding them. Just turning them on and off. I still think it fits with the theme.
