It looks like a fun game, but according to the link, this is only the demo, there's also the full game. I can understand you want the game to be fully free of ads, but I honestly don't mind ads, so long as there isn't a pop-up every minute.
Because of this, I don't want to download it. I don't want to go to deep into a free game, and really enjoy it, only to realize I need to pay at one point. I know that it is the purpose of a free demo, but I'm only playing mobile games when I can't play on my PC.
It's your game, so you do things the way you think is right. I just wouldn't mind a box for ads in the game. Townsmen also has their game for free with the occasional ad, but all of them are gone and you have access to many extra options (such as making time pass faster) for those who upgrade.
Other than that, it sure looks like a good game, and averagely more than 4 stars from more than 100 people proves that.
