Yeah, it was definitely fun at the beginning, haha! You're totally right, but right now I have so many fronts open: vortices, area fissioners, double catalysts... maybe triple? Balancing all those variables at once without breaking the game is going to be a challenging and somewhat tedious task.
Thanks a lot for the feedback! I'm taking notes on that prestige system or production rate upgrades for the late-game; it's exactly what the lab needs to keep the momentum going!
