first off, sorry for the inconvenience! :( I'm working hard on fixing these issues in the upcoming release. Can you post the error messages? That would be a good starting point for me to help you.
Hey Starlit! i just realized after i fought the boss, the game just actually goes on and i think it is already fixed... haha btw this is the first time i play such great a long game like this! I still haven't finished it though..
