Turret Defender

Game description:

"In this tower defense game, you can only place turrets in specific locations. This can be a bit limiting for veterans of the genre, who may be used to having more freedom in where they can place their defenses. However, the game does a good job of providing a challenge, and it's still possible to succeed even if you're not able to place your turrets in every optimal spot."
