Had real fun playing this entry! Creating wind turbines / gravity rings makes quite some fun. And having an alligator fly through them bouncing off the walls is nice to look at :)
The visuals are nice, but what I miss is that everything snaps together. Some elements have shadows (alligator, trees, ring) while others seem to be either fully lit (fish, all particle effects) or fully in darkness (ground). The water seems to have an gradient while everything else is flat. The eye seem to be drawn to the mushroom bases (glowing in yellow) while they are not that important. The splashes of the water have the color of the glows instead of the water. I think adding a vignette wouldn't hurt.
The gameplay feels like a fresh mixture of Flappy Bird and Angry Birds :D
Makes lots of fun and a really great work from you! Entertainment: 5 ✯/✯
