Having played through this, I like the premise... but I notice a bit of an issue. There's no point to doing a prestige excluding deep roots and the one achievement. Decay rate is moot unless there's nowhere for new items to spawn (0.25 decay on 30 items gets just as much rot as 1.00 decay on 30 items,) the ones that permanently unlock upgrades come after you've already unlocked those upgrades in the run so you'd have to reset to lose them in the first place, and double nutrients comes after you most likely have cleared out the shop of upgrades.
