i found a problem with arrows keys . it's not WASD but WQSD with a qwerty keyboard .
I'm french and use azerty , normaly it's ZQSD, but with this problem it's AZSD.
and this game is a good idea .
Thanks. We have uploaded a new version with the right keys with a azerty keyboard.
In the english version (with a qwerty keyboard), the keys was right.
