clever design and implementation of the theme. elegant in appearance (proof that primitve assets can be the most appropriate) with perfect music*.

some suggestions to make play more enjoyable:

• the instructions aren't clear in that the box also wraps/loops around the level while i first thought to "drop" the box onto the target below (level 1). ability to Push through the loop also not mentioned ("walk").
• [Enter] to Restart level (which also seems to initiate another instance of the background music (at least on the first level the issue is consistantly reproducible).
• save progress so we can pick up where we left off (and an [Exit Game] key/button so we can take a break easily enough).
• view/perspective could be a bit more top-down to relay the entirety of the levels (or camera rotation).
• let us hold WASD/Arrowkeys to Walk vs separate presses (keep Push as-is).
• while some of the levels were well designed, others, like this, left me perplexed. with a first move of "down", i looped to the right and completely behind the boxes (or inside one of them?):
• 

otherwise, the game is FUN and shows a lot of potential for being more-so.  perhaps we both could get our entries prepped a little earler so we can take feedback like this and make our projects even better (easier said than done, right? alas, that's what post-jam updates are for) :)
