Something I love: I love your main menu and the overall look of your game! I love the rewind system and other world system!
Something I wish your game had: I wish the music for your game continued on a loop in the background while I played (I really like it lol). I think a click E hovering over the portals when you get close to them would be a nice touch!
Bugs found:
1. Not sure if this is a feature, but the boxes can clip into each other
Overall: I loved your game, super cute and fun! Keep up the great work!
