If you are thinking of getting Tower Wars I was in the exact same situation as you.. It's like a Tower Defense but it adds quite unique features in my opinion, such as the Meat vs Machine gamemode where you can spawn your own minions in and handle strategy that way. But to further explain it quite simply I just made a video on YouTube of 10 minute gameplay. Would be super glad if you could check it out.
I do run AdSense but the small amount of traffic I get daily doesn't really do much so I am not in it for the cash.
If you have any suggestions on how to improve my videos or just happy comments then feel free to let me know!
