Turtle Invaders By Zyrobotics LLC is a fun remake of the classic invaders game. It is very similar in play to the classic without stealing any of the graphics or timing.
Turtle Invaders By Zyrobotics LLC is actually pretty hard. Your octopus can only shoot so many ink dots and knock out so many turtles. Turtle Invaders By Zyrobotics LLC is fun though. My daughter played it for quite a while and even comments in the video how hard it can be. Just hard enough to get her to keep trying. Good job.
Just about all ages, but perhaps 6-10 would find it interesting.
