This is pretty polished and I definitely appreciate the fact that you included the F key to pick up the box and put it back down. Sometimes people forget about quality of life additions during jams, but yeah, if this is a game about pushing boxes but there's nothing hard about actually pushing them, then let them pick it up. I do think that the dialogue system could have been polished a bit though to allow skipping, especially since the scroll speed is very slow and if you trigger the same dialogue twice by accident you have to read it again (I read very fast so it's painful to be held back, and it's especially important when the game is designed to be replayed at least 3 times, since a lot of it will be repeated). But the rest of the game is fine and the sprites are very cute.
(I was able to squeeze myself into a wall, as in, between both ends of the wall...how is that possible!?)
