Ah thanks man, I didn't think about the mouse controls, because I tried to optimize it for a gamepad.
The music was kinda tricky to sync it nicely haha, but I have around 7 years of FL studio experience. So I try to make sound/music as good as possible to compensate for the rest.
I'll try to come back to this game if it gains more popularity and make those changes. For now, the traffic is just too low to invest in it more. Thanks for giving some good feedback!
