Australian developer Halfbrick will be releasing their action-arcade game, Echoes–which has already seen an XBLIG release–on the PlayStation Store as a PSP Mini. The title will cost only $2.99. With a total of four game modes (Arcade, Jackpot, Survival, and Clockwork), players control a girl named Charlie after she is transported into a dream world where Echoes mimic your previous movements. The objective is to collect crystals and move strategically so that your movements cannot easily be followed.

At first, the premise of the game sounds simple but after watching this video, it has become apparent that this will be no walk in the park. For more info on the game, visit Halfbrick’s official website. The trailer, on the other hand, is after this break.
