Yeah, working on fixing these today (they should just be in the online version for now). I have just switched to compiling the game with Tweego, and there are a lot of growing pains around it.
But now, the game is open source! And we have added some tools for people to be able to mod the game more easily in a non-hacky way using a custom mod loader. A number of people are working on mods on the discord, and I think eventually we'll have a thriving roster of mods for people who want to add specific characters or content.
This is the code repository now, for anyone interested in checking it out:
