Took me some level to wrap around the fact that you reverse wall and empty space around you. But after that it turned as one of the best puzzle game that I played so far in this Jam as all the rooms don't seems to have a single solution but you can really remake and reorder all the room around ! The mechanic itself carry the game but the sfx are quite good and the minimalist visual go really nicely with the rest of the game !
Really nice entry, Great Game, Keep it up !
