Haha, if you're curious, the way I came up with the idea was super serendipitous but somehow natural at the same time. I only got started with trying to make games recently, so when the jam started the only thing I knew how to do in unity was move a sphere with a rigidbody around using the arrow keys. That pushed me towards trying to do a physics-based bullet hell, where you're a sphere trying to avoid being knocked off a platform by a bunch of flying objects, since that felt like something I could reasonably pull off.
I was in the shower thinking about level designs for this game when I came up with the idea of a pool-table shaped map, where you would need to avoid being pocketed by a bunch of balls rolling around. I really liked this concept, and it got me thinking—what if the entire game was pool-themed?
That question took me down the path that eventually led to this game. I honestly had no idea if the game would even make any sense at all, so I was incredibly relieved when I played my first 'tech demo' and it was FUN.
Thanks so much for your comments! That vibe of making you "feel like you're making the best shot of your life every time" was exactly what I was going for with the music and the gameplay, so I'm really glad to hear it worked for you :)
