- (Yes, the second player is moving automatically)
2.) This is something not very important but sometimes the bothers me. With the SMB3 exit, the level ends as soon the player goes off-screen, but, the level should ends when the player goes off-screen and the sound effect ends to play. The duration of the sound effect is 4 seconds, so I would recommend don't let the player finish the level until these 4 seconds happens and the player is on the end of the level, of course.
3.) With the SMB3 exit, when the player completes the level, there's still a visible part of it, I'd recomend make the player walk a block more to the right when its off-screen:
- Wait, wasn't this fixed?
4.) When the player fnishes a level with the flag exit, new path won't appear in the world map
