In the menu, hover your mouse over the pictures of the ball types and use the arrow keys or the scroll wheel to change types. Click on it to add it to a side. Do the same process but on the "change to preset" button to change the preset. Click on the buttons with the numbers on them (not the numbers specifically the button) to be able to change the value. Click start simulation to start the simulation. You can also drag the pictures and the change preset button to change it aswell. Custom Menu When clicking the "add custom" ball picture, you get led to a custom menu. Click the "add properties" to add properties. Slide the bars at the bottom to change the color and brightness of the ball. Press the arrow key or drag the ball on the top left to change the ball color preset. If you are on the "custom" type, the layout becomes a bit different. Click the "change color" button to change the color values of the ball by putting in hex codes. String multiple together to create fusions. Click the "symbol" button to change if the ball as symbols (phi, n^n, n!, ect). to change the sound for the custom go to a different ball color preset and click the ball and go back. The sound will change corresponding to the ball you clicked. You can also still change the color values on the different ball color preset to change the color hit effect of the custom ball. (Oh and for hyperfactorial change the l to a captital I for it to work) Click the button called "ball properties" to list all ball properties and click again to close it. Press "o" to open it as well or "x" to close it. press the right or left arrow keys to scroll to the right or left of the list. Like the other things in the project you can drag it as well
