iScape Games let us know that they have released their first iPhone game: Super Marble Roll [iTunes link]. I know... another marble game, but I think this one deserves your attention. I have spent a little time playing Super Marble Roll and find the controls and implementation of the accelerometer to be phenomenal. There is also a special easter egg "bonus mechanic" included that'll help rack up those points!
iScape Games also shared with me that they already have updates planned for the future and are discussing more features such as unlocking levels and stage achievements.
Super Marble Roll is available in the App Store for $2.99. If you pick this one up, let us know what you think in the comments below!
