Thank you for your feedback!
The game was designed for French keyboards (AZERTY), so the default movement keys are ZQSD.
On my PC and on another French PC, the controls work correctly.
I will look into adding support for WASD in a future update.
Thank you for playing!
This is my very first game, and I focused on releasing a French version first.
An English version may come in a future update if enough players are interested.
Thanks for your feedback!
