Good Game, but not comparable to other sim Games
This is a really good idea. And the setting and maps are great, but you have a few problems.
Bad Pacing (either the game is going too slow, or it is going nowhere.)
No Story (their should be something holding this together.)
Don't listen to everyone else about the drawings, because that isn't the heart of the game. But this can't be called a game, if everything is so repetitive or not enjoyable.
Those people are just nitpicking. Maybe in a few years, this will be better, but right now, it's a novice simplayer.
