Super cool concept!
I get some errors when trying to run on Ubuntu 20.04:
./mine-or-die.x86_64: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by ./mine-or-die.x86_64)
I'm assuming Godot was compiled on a newer Linux than mine or something like that?
I was able to get it to sort of work through Wine, but it didn't capture the mouse cursor, and so I couldn't turn around all the way, and basically just got killed by enemies from behind eventually :-)
Anyway, this is a very ambitious game for a game jam! Destructible terrain in 3D and a crafting system?! Congrats on pulling it off! :-)
