thanks for the comments, and for the frame rate, I was planning on a mechanic where you "sacrifices" an amount of troop for a better troop, or to "buy" something like upgrades, so there isn't soo many follower that it lacks your game, or simply adding a limit for how many follower you can have, BTW this game is inspired by "right click to necromance" troops like knight, wizard and golems(but did not manage to add in the golems XD)
