In addition to my previous games/ports (iZoo and Noiz2sa), I have released rRootage which uses OpenGL graphics for the iPhone and iPod Touch. It is a port of another Kenta Cho game, so check it out. It is the result of some graphics experimentation I am doing before my big game which is hopefully coming soon - more details about that one later
check it out on the touchrepo source touchrepo.com/repo.xml (or will be on installer if you have the latest community sources)
Note: it is not compatible with the Dock app (makes the screen flicker).
