Frankly pretty awful from a purely gameplay focused stance. Is it kind of new and interesting and novel? Sure. But that design also locks the player out of and punishes them for trying to experiment, despite that being the intent. The biggest culprit of this by far is how completely and irredeemably useless the prestige system is. Speeding up time? And all it does is increase game speed? No bonus to the speed at which actions are completed? So you mean I get to skip to the part where I lose ten times faster with even less possibility of being able to make conscious decisions. Get more experience points? Sure, bonus points are nice, but they can only be spent on speeding up time and getting more bonus points. Excuse you? Having tight margins is nothing new, not a bad thing either. But when the entire feedback loop is broken it needs to be replaced entirely. Even with the few scraps of conveniences the player is offered, you'll still waste hours and have nothing to show for it.
Worst of all, the main "feature" advertised for prestige accomplishes literally nothing. You will still spend the exact same amount of time you normally do scrolling around the map and clicking things. It still demands the exact same amount of player focus and thought power. It still requires the same amount of strategic thinking. You still cannot take your eyes off the game. It doesn't select the next task any faster than a human could. And worst of all it's prone to jamming up; if you miscalculate or just have a momentary lapse in attention, you can expect to find it stalled out on some random task a fraction of the way through the run. You MUST babysit the automation.
This game cannot be left to its own devices while you do something else. This is not an idle game, and barely counts as an incremental.
