LOL I kinda feel the same, I started an on screen overlay tutorial... then it introduced new bugs into my already playable game... spent another hour then end up stripping it down to just text tutorial guide... I don't have time to work on more as I have to work tomorrow... but just like you... i was like why don't i put in french... as I am in Canada and it is one of the official language which I am still learning ... Anyway, half way through it... realized french keyboard is different ... LOL I already had enough issue dealing with navigation on both desktop/mobile controls for my game so I gave up that too... looks like you have achieved all that I wanted to do!
I see your game is a Windows game. Would you be able to work on a web version so we can try?
Thanks ^_^
