After being surprised of finding the game on the appstore yesterday, I’ve found out that Sega actuall announced this game properly. I already spend a full hour with the game and it is quite good. A review should come in the following week. Anyway, have a look at this trailer to find out what the game is about! Also, there is no actual gameplay shown, but the style is close to what can be found in the game.
