Whoa, that is so cool I love the flipping mechanic, that is really interesting! Also, the fact that enemies stay dead is nice (maybe a little too rewarding sometimes). Also I love turtles. The snow particle effect in the background was a nice touch. One specific complaint is how in level 3 there is a wall of spikes at the end of a hallway of saws, I got mad at that wall of spikes. But the best thing about it was how polished and well-rounded the game turned out! Good job.
