This game is cool, but I don't see much incorporation of the theme. I like the idea of a tower defense where you have some input on the tower, like with the shield. That said, there were a few issues. 1st, the controls aren't immediately obvious. Also, there is a lot of information left for the player to figure out on their own without help. Like that when the enemies hit the shield, they still damage the tower. I also didn't know that I could move the shield until I tried shooting through it, and pressed a bunch of keys to try to move it. Another issue, is when you lose, there is no button to go back to the main menu, the player has to try to figure it out themselves. Then, the exit game button did nothing for me, and had to task manager out of the game. Overall, it's a cool concept, just a few problems that make it slightly less enjoyable.
