Your code throws an error in Lua. You probably want to reverse the arguments to math.random if you're trying to get a random number between -100 and 100. You will see similar errors when running your game using the native love executable.

Thank's for the short response

I have understand the probleme i'ts because love.js use standart Lua and Löve use luaJIT

@spectrenoir06 Ah, very true. That's pretty weird. Thanks for figuring that out!
