Very cool game! Very fitting for the game jam and very satisfying to play. The dimension drawings are cute and easy to tell appart form each other o it is easy to choose the correct one.
I dont think I feel any difficulty increase in teh levels; the last one with 2 portals was hard because I had to wait for te portal to clear out but the next ones got very rowdy at teh end and hen you start the next one it seems calm in comparison. This is not a bad thing for a short jam game but idk if it is intentional.
Also, idk if the dimensions sorted in 3 groups is a good thing or a bad thing. I feel like having to mix all of them together (like, one customer ask for 3 ones but they all are from the first group, for example, and another one ask for 1 for the first group and 2 from the second one) will give more variety but it may also make thye game too chaotic. I dont know if it if thats something you already think about or not.
