Hi, nice game. I maxed out the demo.
One thing that I notice that I don't know if it's intentional but the cycle speed cost is lower for each upgrade, so you start requiring 5M and the last upgrade is 1. something M
That was planned all along ;) I didn’t want people to have to wait more at the end of the demo and end up hesitating between buying this upgrade or buying the last square to finish, so I wanted to be sure they would buy all the successive cycle speed upgrades as a sort of final explosion of production…
