★★★☆☆

pretty sure the ad for this said it was a traditional tower defense game. IDK about you, but I consider that to mean you place towers of various sorts to deal with the ever increasing waves of enemies as they travel a winding path to your base. A decent game in its own right, but false advertising.

I've been playing for several months, and I've become fully addicted. I've spent hours grinding. This is one of those games in which it becomes more enjoyable the higher you get. The game is perfectly balanced it never becomes easy. It's a challenge at any level. If you want to play a game in which you're constantly challenged, this is the perfect game for you. THERES A LADDERBOARD, in which you'll always feel eager to play to go higher. PLEASE add more monsters and maybe bows, content, or ideas

This is not a TD game. You are actively aiming where you want to shoot. For me that is a good point. The devs designed it so you unlock features little by little. At level 50 you unlock all the features... After that, it's just grinding to earn resources and upgrade your defense systems. However, there is where strategy starts. You have a good amount of different crossbows, traps and spells, but limited amount of spaces to place them; so, you cannot grow infinitely strong. Choose carefully

So... can we talk? the goodness is the game runs fine without crashing. But... there's very little to it, the graphics are poor, the sound isn't horrible but not good. The music was a pleasant surprise, usually it's the first thing I kill, but I left it on through level 60 some. Remember when I said there's not much to the game? well, that took me 65 minutes, including playing several infinite levels. its not bad... to damn with faint praise.
