Resco has released the first commercial game using HTC’s still unreleased accelerometer API. Bubbles is an action puzzle game where the idea is to clear the grid of bubbles in order to advance to the next level. Control the steel ball by tilting the device and try to pop all the bubbles in the order from the lowest to the highest numbers. Try to do that as fast as possible and avoid all the dangerous bubbles. Numerous explosive, speed-up, slow-down and damage bubbles keep the game play exciting and challenging. There are 30 levels with different arenas.
This application is an interesting development, as its restricted to only the HTC Touch Diamond and HTC Touch Pro, which form only a small part of the windows mobile universe. As the G-sensor API is unpublished, there is also no guarantee that the API will not change in later devices or even ROM updates of current devices. These issues underline the need for a universal API for the advances sensors in new Windows Mobile devices.
