A very enjoyable game. Good levels, but I found even the last ones "too much" easy for someone experienced with platformers like me. A bit of difficulty would make this game even more enjoyable. And using the hookshot is simply awesome!
There are a few bugs, e.g. in the final stage of Level 3-5 sometimes all the enemies disappear, but they aren't annoying.
Very funny characters and the atmosphere reminds me of Adventure Time!
