First of all, thank you so much for the OpenGL 3.3 compatibility.
Now with the bugs:
1. Language settings: there's no change when changing the language to non english.
2. Graphic settings: there's no change when changing the resolution in fullscreen, it's until you change to windowed that the change is visible. I normally do this with more demanding games. but in this particular case I don't see a real problem really, I'm just reporting it because is posible to do that combination lol.
Overall this game feels very well polished already. I'm looking forward to see your future progress :D
