This game has a good amount of content, and I love the “polynomial growth, but with a time limit” concept - reminds me of “fighting time” from the last jam. Unfortunately, I think this game is too slow and linear. I’m just pressing buttons in the order I’m told to, with no amount of choice. The order of upgrades is very nearly entirely enforced, due to the time limit making it so I can’t even decide to idle towards the next goal. This applies through probably the first 3 factories. Technically the city tab is non-linear, but from my experience it doesn’t make enough of a difference to impact the actual gameplay in the factory tab.
So I like the amount of content, I think there’s just too long of a wait between seeing it - especially needing to do multiple factories before getting enough to buy something new in the city tab. After the factory tab gets mostly automated, my time is just spent occasionally checking if it needs me to reset the loop, or buy a factory upgrade. Frankly, it’s boring, especially doing it for as long as the game expects me to.
