Love the game!
That being said, I'm stuck on the first square of green. With 18x to collection and 13x to speed, im still stuck only getting 24 RP per reincarnation and many of the later upgrades seem super far away, especially since I have to do everything manually. Plus, many of the merge crystals scale faster additively than merging them, so i can only realistically get 2 more crystals per reincarnation. Any advice?
