Really cool! Glad you went ahead and finished it :) I could not defeat the Royal Knight however, seem's I am... unworthy of the title!
Ey we took into account your feedback and we reworked the game with these update:
Progress is not lost when defeated jousting.
Progression speeded up.
Stats and Items explained in-game.
Exp and gold obtained shown in menu and Victory/Defeat panel.
Royal Knight is the strongest.
Fixed horse running sound clitch.
We are happy to hear any feedback on the current version, thanks!
