Its a great game, and I play it every day, but it has some flaws. For example it is very hard to put towers just were you want them, unlike in Bloons TD were you can fine tune exactly were you want it, enabling you to put more towers in a smaller space, maximizing the amount of damage in a set amount of space. Also, the towers are rather plain looking, and combined with the drab look, every level looking the same, and stupid background sound effects makes for an unappealing game, when compared with Bloons TD bright colors, quick action, and peppy music doesnt create much of a competition. Also, unlike Bloons TD, every upgrade is the same and does different things, and may even grant new abilities, wereas in this game, every upgrade is the same, with every tower being the same, save for the cost and how they fire (with the exception of the ice tower and the poison tower). BUT, it is a great game and idea underneath all those flaws and problems, you just have to be willing to dig and find it, which most consumers arent willing to "waste their time" and do.
