Great game! The art is incredible. Just wish there were more than 1 enemy. Some things that would improve the game if you were to make a full version:
1: jumping / wall jumping is a tad jerky, for example you instantly stop going up when you release the key or you instantly go right after a wall jump on a right wall.
2: Try adding some sound effects to dialogue to give it a little more presence.
3: You should totally have some quirky dialogue about being able to carry an entire freaking mast out of the cave, and then dangling a dinky little hammock from it as a sail.
