It was too long and it didn't have much of a story
I didn't get it... Why would this guy waste his time getting back his octohedron when he could make limitless amounts of useless octohedrons with his hands, and how did he get it to fly???? That was when you lost me, the only scene that I loved was when he got to that place with the bird's nest and the crazy mountains, I liked the overall mood of that place, everything after that was horse rubbish! He should have thrown the princess into the ogre's mouth, not tasteless octohedrons, and I was waiting for the whole story to have a point at the end, you know like a bunch of random stories that all converge into a climactic ending, but no... it was only the birds at the end, booo. I admire your animation skills but this thing had way too little action, humour a 3 year-old could enjoy and pretty much the whole story SUCKED... good skill put to waste.
And what's up with octohedrons??? I know you only listen to Classical Music in your spare time, but octohedrons???? could your lifestyle be anymore nerdier??? preppy.
