It’s really simple, but I found myself clicking and playing for longer than I expected.
To be honest, the math went completely over my head. I have no idea how you achieved this. I was basically just clicking the green buttons on Main until I couldn’t anymore, then collecting the endemic points, upgrading Endemic, and repeating the cycle. I’m still at 28% Pandemic, so I haven’t reached it yet.
That said, I don’t really feel like there’s much strategy. For example, I don’t think clicking Case Gain before Population would make much difference, so it ends up feeling a bit linear. Even the upgrades seem somewhat guided, you can usually only buy one or two at a time, and they’re typically the ones the game suggests rather than ones you choose strategically.
Still, it’s a very addictive game and a classic incremental in the purest sense: exponentials, simple UI, and plain text buttons.
