According to Touch Arcade's preview, the items and characters you seek out all have their own behaviors. "Many just sit there. Some move towards you. Some (like jiggly bananas) dart away from you. It's a bit chaotic. And the elimination of each character triggers the next note in a haunting piano melody."
Neither Touch Arcade nor Minter provided a date for Deflex, but it appears to be done, and thus likely headed to the App Store soon. Check out a video after the break, and don't think for a minute that our description has prepared you for the weirdness.
