Thanks for the comment and the bug reports <3
The last "combat not loading" was because the mimic was using the description file for a different monster, which didn't have a description for one of the mimic's moves, so it crashed.
I can't find why the troll cave might be failing now! It's the first quest I made, and it's super basic. I'll have a look.
Fight club was a quest to test a bunch of additional features I added to the code - moving the player around the map, offering different options that change how the map works, etc. I'll look at that one too, but it might be a more complex fix...
As to your Side note: This game started as a Twine game, before the complexity of what I wanted to do started getting out of hand in an engine intended for CYOA stuff. So I taught myself Unity + C# so I could remake it. The previous version was text only, and had a couple of features that aren't in this one yet (mainly the companion you could hire who would fight with you and get corrupted by monsters) but the new version has almost all the features that one had, and will have definitely more content when I'm finished with the current update.
