Did you make the music too? Not a bad beat.

Some added disparity between the floor and wall texture would be good. Was kinda hard to see when there was an opening into an adjacent room. Being able to break boxes with the pick would also have been a nice feature.
The enemies didn't entirely disapear when they died, probably a known bug. But they also wouldn't die if they were continuing to be hit which was confusing, you had to stop attacking for them to die.

I am not sure how the attack works, so it was a little frustrating playing it, but good idea.

Attacking the enemy could be more satisfying, right now it feels a bit bland. Also pushing the box could be stronger and feels smooth. Now it feels very draggy. However, nice concept. Great effort!

To be completely honest, it seems like this game was a victim of scope creep.

Open world games (even small, 2D ones like this) aren't really a good fit for game jams.

Commendable effort though.

I don`t know how to play XD
