I am really happy you enjoyed the game.
Currently I am working on making the game more solid (less crashes, fixing the bugs that you mentioned, better performance, etc).
Sadly multiplayer nor customization are planned to be worked on soon, instead I am focusing on more worldbuilding, structures and improving the world so adventuring is less tedious and there are more things to do. Any ideas you may want to share about this are appreciated :D
Thanks for the feeback!
