This game deserves more recognition. It is on par with the Kingdom Rush series. The Hero system in this game is better than KR - more in-depth and more upgrades with equipment to purchase. You can even use 3 Heroes at the same time. Love the humor and the fact that the Heroes taunt and say things mid-battle. My favorite part of the game is the addition of gibs filling the map as enemies get destroyed. Really gives the game that over-the-top feeling!
Game now runs noticeably slower on older devices (4S) with the new update. There should be an option to revert the graphics to the way they were before the update: option to turn off shadows and casings.
