Despite its name, Urp! doesn't look like it will give you indigestion
Unless you watch the trailer and eat everything that it shows up! Hiyoo!

While the art is a bit stock standard, the level design looks quite impressive, using the different layers, and maze-like paths of the entire rotation of the level to the game's advantage. Exploring might be as enjoyable as solving the puzzles. Urp! is available in the App Store right now for $1.99 (AU) if you're interested.
