Very fun and addictive game.

That's a very cute octopus!

I liked that you even created context for the game, that's a great touch. At first i was a little confused because i didn't see anywhere what the controls are (maybe you specified them somewhere but i didn't see them), some of the walls of the level are almost the same color as the background in the first part so be careful with that! Lastly i would like some music in the background but overall, great work!
