The game was suuper fun to play, and caught me by surprise cause I didn't really expect it when it started. The flow of the level was really nice and the action packed run and gun aspect of it was lovely. I liked the rotation of the square and it's 'floatiness' a lot. To be honest I felt like there is no need for rewinding. Also I had no idea how to open or how did I open the blue "door" things, sometimes it just happened, and sometimes I felt stuck, maybe I'm just dumb.
With some tweeks, the game could be really good, keep up the good work!
