Good grief this is bad. I love tower defense games, particularly RPG-based ones, but here the RPG elements are way over-blown (virtually non-existent); in-app purchases are not a luxury but a requirement (bad form for a paid app); and there are extremely limited strategic options for a modern tower defense game. Save your money for any one of the many, many better tower defense games currently on the market.

With the newest update now you can use the gems you have to buy with real money to upgrade towers with still now fix to the lack of space to build enough towers to actual survive the 3rd world. I want my money back this game is just a complete waste of time.
Whoa whoa whoa whoa butttt
Before my review, I want to get something to the developers: Please let me listen to my own music while I play, also please let it work while SiriusXM radio is playing. Review, 5 star for anyone that plays tower defense games solely for the change up in playing style. The change is more different instances with fewer levels to beat per. Def a must for td enthusiasts Other must haves Bloons TD 5 TowerDefenseHD

This is a great tower defense style game. There is a bit of strategy involved with a lot of upgrades to choose from. I have a lot of tower defense games because they are my favorite ones to play and this game is in my Top10. It's more than just build a tower and shoot. If you want something that takes a little bit of thinking on top of a basic game you will enjoy this app. Don't listen to all the naysayers this game is a lot of fun.

Would gladly give it a 5* rating but the costs for a decent chance at winning levels are ridiculous!! Its a shame someone actually felt the costs were reasonable... Not even close.

This started out as a promising TD game then the updates came. Yes, they added new levels but they also added IAP. I have nothing against a developer making money on IAP, but to make a game dependent on it just ruins the game. This is, after all, a paid game to begin with. Stay away from this one, there are plenty of legit TD games with IAP, this isn't one of them.

Plenty of fun upgrades. Increased difficulty keeps it interesting. Over all worth it for .99.
