welcome to throw rock at wall Hold space or Hold down your mouse to start spawning rocks, each time a rock hits the wall you gain money. The first upgrade is the wall upgrade - Each upgrade gives a multiplier to your money. The second upgrade is the rock value - It increases the value of the rock when it hits the wall. The third and final upgrade is spawn speed - It reduces the time it takes to spawn rocks. Change the background colour and enable or disable the trail in the settings.
If you find any bugs tell me and ill try and fix them!
