I think the concept here is good and you can definitely see the potential for future iteration. The main thing I struggled with while playing was the fact the balls spawned at such an enormous range. For example a ball might spawn looking up then a ball looking down all the meanwhile being in any of 360 degrees. That's a lot of spinning and pitching! Tweaking the ranges would help a lot I think, along with spawn timing. Other than that I think it's a clever use of the asset pack. Nice job!
