I like the Portal-inspired vibes you have here. The graphics are cute and controls work well too, except for some Unity platforming jank. I really think your game has a lot of potential- the rewind mechanic combined with falling cubes and buttons is something worth exploring. I would try new things too- maybe certain objects are immune to rewinding, or maybe they act differently each time they are rewinded. The text to speech was kind of funny, but consider replacing it with just text. You are taking a lot of inspiration from Portal, and although that can sometimes be a good thing, you may be limiting yourself to certain ideas and mechanics. I really want to continue playing this game because there are endless possibilities, so please consider developing this further post-jam! If it's not too much trouble, I would really love a review on our game if you have the time!
