Buggy and unbalanced
I downloaded the demo and tried the first level on easy. With the amount of gold coins they give you it's extremely hard to beat the first stage. I don't take issue with the game being hard, but it' the first stage. Give people a chance to ease in and feel like we are doing a good job then hit us with an absurd amount of enemies.
Also, most tower defense games have a similar formula; hit the enemy at the head of the line. The dart towers in this game will randomly turn and shoot other enemies behind the leader when the leader is clearly in the radius of the tower. That is frustrating.
The problems are enough for me to pass on this.
