That's a shame, but I understand. What you have there is already great. Hope you decide to make a sequel one day.
The kobold battle music lasted through out the rest of the game. Finished some quests in the camp, fought some more enemies, but the music never ended. There was probably some enemy stuck somewhere.
I use czech keyboard layout:
Rebinding works fine and switching to eng keyboard layout does the trick too. Anyway, this is not just a problem with your game. I have the same problem with some bigger games too. Most of them seem to be in the U4 engine.
I played a little more and found another possible bug. Dryads in the swamp get stuck after the first parry and I can just hit them over and over without them retaliating. Also, "test" starts appearing in the left corner when that happens.
Tried talking to mercenary leader and he works alright. It's the guard leader who just lets me join instantly and gives me all armor pieces for free.
Anyway, I really like your game. Will wait for you to patch those bugs and I will try to finish the whole thing.
