PC/Linux: Press Shift + G in the game. Change the renderer to any other option, you might have a OpenGL or DirectX issue. Exit and relaunch the game to ensure best results.
Android players: We've tested the game and it works, but you could experience lag or other issues depending on the phone you're using because the game has gotten very large. It's recommended to use Joiplay and play the PC version within Joiplay (requires 6gb if device internal storage -- not SD card "external storage"), which will make the game run smoother.
