This is a pretty interesting and stylish puzzle. I donāt have much to say about presentation beyond that itās great, so Iāll focus on mechanical stuff.
Control scheme felt a little frustrating. You would usually use [Space]/[W] to jump and [E] to interact.
The main point of frustration for me was that it is quite easy to softlock yourself. Sometimes keys get stuck in the unreachable place, sometimes you mess up and objects grow too big and get stuck, or gets janky because of physics. I think the level that introduces bumpers is the worst offender here because in addition to that one of the keys will not fit the door. And replaying a level after softlock takes quite a long time.
The more control over tossing objects would also be helpful. Although once you understand that object consistently rotates depending on your direction it becomes easier.
Iāll be honest, I didnāt finish a game although I got quite far. Since the only mechanic you use to progress is tossing objects between dimensions to make them bigger, it gets repetitive quite fast. The dimensional box adds some variety, but for me it wasnāt enough to offset the frustration.
Overall, itās a fun and funny puzzle, and with a bit of polish will be a great game!
