I really enjoy this type of game. Sadly the autobuy not being an option has completely ruined it for me. I've stopped playing after unlocking the autobuy even though I want to see the rest of the content.
Fun: 4/5
I think for me this game would be 5/5 if the auto-buy thing didn't happen. For some info about why I despise it so much, I feel like it took away any interactivity I had with the game, everything is just auto-bought. It also removes any choices I could make, such as buying the best upgrades first, everything is just autobought. And finally, I reached a point where I had enough money in a loop to "prestige" but the autobuyer was not allowing me to get it. I think I was making probably around 8k in a loop, and a new city cost 5k but I couldn't actually get it because my money was being spent.
Anyway other than that, I enjoy the pacing of the game, and even if it is fairly linear, I don't have issues with a linear incremental game that has short downtime between upgrades and seeing progress.
Balance: 4/5
Early game felt pretty linear, as stated. Nothing felt too slow though. I like how it started branching off and you could prioritize certain upgrades before the auto-buyer took over, to optimize your money/loop.
Some city upgrades might be a bit too strong/weak compared to others in their row.
Uniqueness: 4/5
I've seen some looping games like this, but I would still say this is fairly unique. Nothing extremely new or anything, but it's not a complete rip off of AD like a lot of games tend to be.
Theme: 4/5
Fits the time theme pretty well in terms of looping time.
