I really enjoy this game. Games with upgrades are very addictive!

Please, dont turn into scam, you are really cool guy
Interaction between players would be really cool, I also recommend to add refferal system to improve players amount (believe me, its great promote way). I think good thing would be rewarding for promoting, like gold for making video about game, but you would need to review it by yourself :p

Anyway, good luck. Hope that site is making income to you!

I see refferal system is already here, my bad
