Sonic Jump Fever out now!
The 'sequel' to Sonic Jump is now available in the Google play and Apple store, called Sonic Jump Fever! It keeps the original Sonic Jump formula intact, while giving it several new additions.
In another mobile Sonic game, named Sonic Dash, you could challenge against your friends for the highest score. This is now also a new addition to Sonic Jump Fever. Another upgrade is the Fever option, which is simplified as the overdrive mode of this game. Chao's also make an appearance in this game, but don't get your hopes up. There is still no Chao Garden if that's what you were wishing for.
Best of all, the game is completely FREE!
