What an impressive game! I played through all 9 levels and think level 6 was definitely my favourite!! The way you have implemented the theme of rewinding via death but having things remain changed is brilliant and the level design and way that the mechanics of the game are taught to the player is excellent. I liked the basic nature of the sprites and think the blood particles on death was a really nice touch. The dev should be very proud of this submission as it is one of the best submissions I have played so far!
