The concept is fun, but it's kinda hard to keep the pinball inside the loop, you need to always stay on your toes to not lose the pinball.
I think I found a little bug with buying the bumpers? When you click to buy, if you dont place the bumper on the loop and buy another bumper, the previous bumper disappears and you have the next one, losing the previous bumper. But thats a small thing.
Overall, nice artwork and game feel, a little hard but when you get the hang of it, you can keep the pinball much longer on the loop. Good job ^^
