A nice game. Worth playing, would even pay 2 bucks for it, after some modifications...
It should be more easier to construct and remove paths.
I can't upgrade facilities, just says not enough money even I have like 10 times the money needed. Do I also need the experience?
Also there is a grammar error, it says " one of your janitors is take rest" (should be "One of your janitors is taking a rest.").
After those and some other flaws (like the pace of everything like other revies say) corrected the game would be 4,5/5.
