The image and the headline are all we know for now, but based on the name and platform it looks like Sonic will soon be entering the run and jump genre. To be honest, I don’t know why SEGA hasn’t done this sooner. Sonic the Sketchhog and Nike had run and jump Sonic games, but both were free promos available to play for only a limited time. This time out, they might make some money on it. Either as a free game that relies on in-app purchases or an inexpensive one time purchase.
Edit: I just realized that Sonic Jump was in fact a mobile phone game released back in 2005, which played a bit like Doodle Jump (released in 2009). So this could either be a port or an updated version of the game. After the break, check out some original Sonic Jump gameplay.
