Imagine kingdom rush frontiers. Okay, now that you've got that picture in your mind, imagine it with a BS energy system, Pay-To-Win "VIP" Levels and having it cost a king's ransom to get a new upgrade for a tower, with being able to spend diamonds on things (1 diamond = 1 kred = 10 cents, some of the cooldowns take a hundred diamonds to bypass) which can be earned very, very, very slowly by playing the game OR by spending money on them (AKA The pay-to-win tactic) which takes a $#!^ ton of money. 1/10, would not advise.
also i think the enemy defense level could be nerfed a bunch. i mean, like, being able to one shot level 106 x 200 vs. 0 damage for level 107! i mean, Why would they do that!?!?
