The font is something I could look up but because I want to keep the pixel style is complicated as not all pixel fonts available for commercial use are compatible with characters outside English and the ones that are, don't really fit all that well for my taste. I will try to find a font that is more pleasing to you but is not an urgent matter at the moment.
As for the incorrect answers, is made that way because is far too complicated for my knowledge with programming and I focus on Game/Level Design. While I could try to find a way to do it myself with time and that way improve how the system works in the game, the easier route would be to hire someone more capable which is not an option as I don't have the money for it.
I appreciate your feedback but right now, unless is something that has an easy way to fix it or a huge bug within the game, I have no plans for further modifications in the game.
