This was a fun one to play! The world is gorgeous and the music and SFX are great. The character controls well, however the key binds are just weird, especially for movement, please add a way to remap them.
I did find a few different glitches, for example items falling through the map when mined as they're pushed by the larger object, I ended up falling through the map I assume by being pushed by an object being destroyed.
Outside of that this was a really solid entry, and absolutely insane for a first game I hope you keep working on this post-jam because this could be amazing!
