Drawing items into the world is fun and clever! I'm not sure I was always using things for the right purpose, even though I was given the decoy to distract bullies, I used it more to gain vertical height by jumping on its head.
In the second area I ran out of ink and couldn't find a way to proceed. Right after getting the leg power up I could jump onto one ledge where I saw a destructible wall and didn't have the juice for a rocket to hit it, and jumping higher to the right led to what appeared to be a dead end. I fell back down and eventually decided to drown in order to reset and try to conserve my ink better, but when the scene reloaded all I could see was a brick wall and it appeared to be constantly reloading with the music resetting over and over again. :(
