I liked the game, it is unique and has a twist. It also doesn't really hold your hand and doesn't overexplain things. It's a mix of a puzzle game and an incremental, and all hints you find through a playthrough carry over to other playthroughs - meaning knowledge is progress in this case. The game also reacts to you using knowledge it has not given you in the current run - just a small line of dialogue mostly, but it's a great touch.
The reason I give 4 stars and not more is because I find the "base game" - the incremental part - very slow and somewhat tedious, leaving the first impression that that is all there is to it (it is not). I'd recommend using an auto-clicker (the third building you get boosts click profits) to get through it faster.
