Thanks for the submission! I had fun cutting down all the trees/rocks and trying to craft better weapons. I think this was awfully ambitious for a game jam, but I think you have a great slice here.
The audio was a bit loud for my taste with no way to change it in the settings, which I understand completely because of the game jam time limits. One thing you could try to do is to normalize to -24 LUFS or something like that for the sounds (works better for music that SFX) or at least compare it to other noises (listen to a song at a good volume for you and then see how your sounds sound without changing the volume).
I also experienced some lag spikes (I played the HTML version). While some of that was likely the infinite map, some if it may also be the shader precompilation (which I found out about after trying to submit my game). You can avoid this by adding a loading screen that has all of the scenes you instantiate visible behind a TextRect (at least that worked for me). Look at https://github.com/godotengine/godot/issues/61233 for more info.
