very nice, the puzzles definitely made me think!
i really love the pathfinding, it's super fun seeing what paths they'll try to take. the third level is the one where it really feels satisfying, where you can see the rabbits merging seamlessly when you successfully clear it.
this is a fun game and the system is very nice, it is held back a little bit by a few quality of life things though.
the ui is a bit all over the place, and buttons/text are pretty massive. when i'm trying to grab boxes, it feels rather strange to have to hover over the bottom bar. i'd much prefer to have it in an toggleable easy-to-reach spot if i'm going to be using these boxes as part of the main gameplay. i do like that none of the ui inhibits gameplay at all, so good job on that!
when the rabbits end up stuck, i think giving the player some feedback that "this isn't gonna work" would be good. currently, it'll just keep increasing steps infinitely. perhaps it could check the next 5 steps, and if the rabbits don't change position, you could give a retry screen for them.
i'd also like some "feedback" to tell me when i've won or i've lost. sure, i can tell i've won or lost, but if I get a victory fanfare? i'd definitely feel like a winner!
i'd totally love to see a fully polished game! good work!
