I dig it! Add in some levels with some tricky decision making and you have the start to a good puzzler. I'd look at the game snakebird for inspiration. It looks like you were headed down a similar path.
Thank you very much for playing! I will try to bring the game to a state which I envisioned at the start. Snakebird was definitely in the back of my head when making this, although I wanted to make the player have infinite length. I'm thinking of finishing it and porting it to android.
