It has potential, but im not really a fan of the shotting aspect of it, specially when it makes the clicking irrelevant to the point that you will rather shoot enemies than click for currency even the passive currency gain seens useless than just upgrading the bounty. Also if the game paused when the menu of upgrades was open it would be quite good since going there to stop shooting when you are like at millions per upgrade is quite risk even when having 4 turrents.
