I liked the game quite much, but you have to fix the save,tower space(really anoying that you cant place the towers in a group),maybe some rewards for getting high points(stronger hero dmg and stuff like that, and maybe being able to keep the hero from the last game to the next game(from 1 "map" to a other "map" to create a little more rpg when it comes to the heroes,btw, u might have to nerf the heroes down a little then) otherwise, good game :)
