It's been a long time since Pixel (Daisuke Amaya) has put out a new game. He completed Cave Story in 2004, worked on the WiiWare and DSiWare ports of the game that were released last year, and put out a microgame for Warioware D.I.Y., but we haven't seen anything in the way of totally new, stand alone projects.
Looks like that's about to change. Jeremy Parish from 1UP got to demo Pixel's new game mid-interview with the game design genius, and it sounds pretty awesome. The game is codenamed Rockfish, and it's for iOS platforms. Like Ikachan (one of Pixel's older games), Rockfish is a simple game with sprite-based graphics, all about navigating through the oceans. However, "simple" doesn't always mean "easy". The first area is based of the opening area in Cave Story, but underwater, and filled with spikes. Poor Jeremy Parish couldn't last more than 30 seconds.
Unlike Ikachan, which put you in control of a squid, Rockfish puts you in control of a kasago (seen above). It will be interesting to see how the two characters differ, not to mention how the game looks and plays. I'll be begging Nicalis for more information on Rockfish as soon as the sun rises tomorrow, so stay tuned.
