A neat experiment, but...
First off, something you're assuredly already aware of but the programming is kinda jank. There's times when two of the same ball are rubbing against eachother and shifting for 5 seconds straight without combining/destroying; and sometimes when balls combine it also spawns another ball up top for some reason? While the glitch squares are an interesting idea, they ultimately aren't very fun in a game style that's largely about precision. The ability to spam balls before they finish falling and the seeming lack of ability to die also holds the game back from being, well, a proper game
as stated before its a solo project and Im still fairly new, thank you for the feedback though, I do wish I couldve figured out how to fix some of those issues in time, currently the only way to lose is to allow too many glitches to spawn in, I want to continue to tweak and update it because I do think there might be something there
