It's a fast paced puzzle dungeon crawler with a twist. To solve each puzzle, you have to kill yourself at least once, then literally walk on the shoulders of those who came before you.
Most of the puzzles can be solved in a minute or two, but it might take you more than that your first time through. Silly but gruesome fun. Don't forget to feed Jeff!
Edit: Just re-read your post and realized that you might be looking for a game you can play on your phone or tablet. LGO is PC/Mac/Linux game. Sorry about that.
For you phone, I would suggest Dynamite Jack or Stealth Bastard Deluxe
