Seems cool as a vibe, a bit tricky to move at times, but that's usual in game jam games.
The only thing is that i literally got soft locked after moving two boxes to my both sides...
Idk if i missed it but a reset button would be super useful.
Also when you pick the key it looks funky, it seems it's interacting with the world in a way that may not be ideal, idk how to fix it but perhaps make it into another "layer" or something that makes it not behave based on whatever tiles are around since it's clear it doesn't work as you intend and it's also surrounded by tiles anyways so...
