Sonic Jump

Sonic Jump is a mobile phone game released as part of the Sonic Cafe service offered by Sega; and on the Sega Mobile service in the USA & Europe, who later released a sequel. In this game, the player is Sonic on a 6-level quest to defeat another one of Robotnik's schemes. There are inter-level cutscenes & appearances by characters such as Tails and Knuckles. The actual gameplay is simple - Sonic bounces upwards off platforms and much reach the top of each level - if he touches the bottom, the game is over. There are 4 different types of platform - regular, disintegrating (one jump and it's gone), spikes underneath so if hit from below Sonic takes damage, and a higher-than-usual jump. Badniks can be defeated by spinning at or near the apex of a jump. Points are accrued by defeating badniks, gaining Rings, and clearing levels quickly.
