So what was grade?
An F? First the music is annoying and there should be some way that you can mute it.
Next, this isn't your fault, but I don't read French, so I had no clue where to start when at the main menu, so I pushed the first, second and third options which led me into this nightmarish epileptic series of flashes between the main screen and this so called "game". I'm guessing that was a glitch. Cause if it was on purpose it wasn't cool.
Next, unoriginal...I despise mouse maze games. They're lame and I have bad eye and hand coordination, which also isn't your fault.
However, what is your fault is this game.
BTW, glad you didn't make more stages.
