RatsLaugh: "Only issue I had was it's hard to tell the different sizes, what I can eat and what I can't. Should make each size a different color or something."
Make the Pallies larger than u red outline. Once they turn edible, turn them green or blue. Food is love, food is life.
Author: "The Pollywog isn’t about reaching a high score, or about buying weapon upgrades. It’s about relaxing and exploring a beautiful world."
Good concept. I would improve it by doing the following: Put your Polly´s position into some kind of global coordinate system. Can probably be done easy by using "distance traveled up/down/left/right". Now, depending on the distance traveled, let a different image of the sea slide in the background (use pictures with few color, so it won´t be too distracting). Once the player reaches a position that lets the picture appear approximately in the center of the screen, he could earn a medal or a "map exploration" percentage. This is for the long term play ;)
About the animation, I would recommend putting more work on the "turning" animation of the character. It looks a bit like a windmill when making fast curves, it doesn´t look "fluid", especially when you become larger.
This game is related to the game Fishy - also on newgrounds - a lot, nice idea
