It took me about 40 minutes to reach the end of Ultionus: A Tale of Petty Revenge and find all of the secret areas, and I have the video to prove it.
I recorded this video a few days ago, adding annotations on the ins and outs of the game. I can't do a proper "Let's Play" of the game, since I don't have a microphone. If you want to watch this video on your iPhone or Android or other mobile device, you won't be able to see the notes I left. (Sorry!)
