Sliders and buttons should be self-explanatory. Click on a slider and use arrow keys to make fine-tune adjustments. Press Space or the flag to restart the simulation and wipe the pen canvas.
Made this over a couple days to fight boredom. Not actually based on those bouncing ball simulations on YouTube, although it definitely looks like it was. From a technical standpoint, the actual physics are done behind the scenes and the sprite just comes along for the ride, in order to fix some visual errors when bouncing at high speeds. Shoutout to my uncle for figuring that one out! #All
