This is due to a webGL memory limit. I just put out an update that attempts to address this.
Great feedback. Yeah, I think RN there's a lot to do at the beginning of the game, but once you have all the capsuled upgraded it's mainly just a waiting game. I plan on adding more upgrades and another item that will give players something to do.
I did have the idea to allow users to create capsule groups. Changing the incubation clone on one of the capsules in a group would change all of them.
The update also introduced orders which I think makes the game a whole lot more fun.
