There's definitely something to this game, but I feel there's a lot to be worked on. Here are my thoughts:
I feel like the overall gameplay loop needs some work. After the first prestige, I never really felt like anything changed. Metaprogression was really slow, I could never buy more than one upgrade, if any, which made it feel like a slog. Things got slightly faster with more pips and the other upgrades, but again, I didn't really feel like anything shifted gameplay-wise. The colors also don't really mean much to me as being distinct, the pips on each rank of color were never different between the three, as they all had equal drain on them, and were equally valuable for upgrades.
The "void" minigames don't feel like they're adding much to the gameplay. It's this whole separate set of things that feel disconnected from the main core concept, hidden away in a corner. Either involve them more in the core loop, or ditch them, because it feels like fluff that isn't really necessary.
There's mention of RTS gameplay, which I didn't get to, as the progress was too frustratingly slow, but this feels like even more of a disconnect from the central gameplay, adding a new separate thing rather than evolving and progressing what already exists.
I think there's a good game in here, but I do think some heavy rebalancing is in order. Of course, these are just my thoughts, but I really think there are improvements to be made. Best of luck with future progress.
