I really really love the game idea on this one. Expanded into well polished commercial game, I would absolutely buy this.
That said theres a lot to improve on the interface side of the game. Sometimes pawns being placed too close to each other and hard to read how much upgrades cost, or even accidentially selling pawns if the buttons were overlapping. And besides that, theres quite a bit of lack of polish that could make this stand out alot.
Other than that, I love the concept so much! ^^
Easy 4/5 for me
