Haha, thanks! Glad you like it. The overlapping opposite color pellet thing needs to be worked around to make it more fun. I suppose as it is, it makes it "harder"/impossible which is sort of the point of this jam, but I'd rather it just be fun. I have a couple of ideas to get around that issue and I will update it soon, just probably not until the jam is well over. I'll let you guys know.
I also need to make it display your score back at the start screen because it is very easy to tap the spacebar an extra time and not see your score. I will fix that before anything else I have in mind.
The little ditty and all of the sounds are just free 8-bit audio clips I got from Unity. I like how lame they are, really. It plays when you go up a level (every 5 points right now, I think). It's hard to notice, but the range of speeds the pellets can have increases with each level. Eventually they get pretty damn fast.
