I have prepared a simple 2d Bubble shooter game. Now I would like to enable multiplayer (2 players only) in this game. Players will use one device so the current game screen must be splited. This is the main task to split the screen and to allow to play by 2 players at one time. Of course the single player mode must be available too. Additionally you must add constant advertisment for single player and fullscreen advertisment (between stages) for multiplayer. The target platform for now is Android only.
