Best game in the universe, do you agree?

the game starts fine and i can play it without any problems but after a couple of minutes the mouse stops working, i can still move it around and it still has the games skin on it but clicking won't do anything and moving the mouse to the edge of the screen does nothing, the music and sound still works, i've uninstalled and reinstalled and nothing has changed...

During my campaign mission called Reunion, while in a realm of water. I tried landing my hero in small island that contain a shell coin. but the problem is, the raft keeps sailing away each time I ordered it to unload my hero there. Any suggestions?

If I bought this would I be able to play multiplayer online?

Why Cant I buy this game anyone know?
