Maybe a passive that increases Energy Matter drop amounts after reaching later waves? because as it is, setting auto-rebirth to wave 100 and doing 2 runs is faster than setting it to 200, but gets the same amount, so increasing the returns for longer runs could make fast farming less meaningful
I'm not sure when the problem popped up as I haven't refreshed the game for quite a while until now and there's been multiple updates, but the auto progress breaks when on a boss level, saying that there is a set number of enemies left to kill before you can advance (it seems to be increasing as the bosses get to higher level) but nothing continues to spawn, getting it stuck unless you hit the next/previous buttons
So far I've noticed that buying the childProcesses and Loops don't actually do anything until you buy a second of them, which on top of not being reasonable, doesn't actually state that, so you spend resources you could use to increase your resource income, on things that don't do anything yet
