Thank you :) Yes there is a problem with the keys and Azerty keyboards. You have to remap all the key at the same as the key is right and not wrong because they don't work. For example, S was the right key on my keyboard but it didn't work, I had to remap the S key, like it was the wrong key (I just click the key, and remap to S). Also the W key in azerty keyboard doesn't respond. If I remap the horn to W, if I press W key, it doesn't work that's why I remap it on an other key. The second problem I have talked about is a sound problem. Sometimes, for some reasons, some sounds stop playing. That's right, in general when I make a presentation, I tried to explain the gameplay and how it works. I like your game and I said it !
PS : thank you for the tip for the neutral position of the gear ;) And sorry for my aproximative english :)
