Fun game, I hit a bit of a roadblock that was demoralising just before I hit the 500k threshold. I think it was a poor choice of upgrades I couldn’t do anything about. It sounds like you’re going to have the ability to prestige in the full release, so if I could have done that, or refunded some of the brain purchases… I think it would have felt more satisfying.
I did manage to break the 1mill in the end though, so it kept me captivated!
