So, I fix the Steam Multiplayer bug, which is working before, but I put the bug right before release. I also add a couple of messages when connecting or disconnecting. (Thanks everyone)

I also rewrite some stage generation to prevent rare barrier bug. Or perhaps I made more bug? (Thanks "Nice Mouse")

I need more input on Mouse pointer being stuck, I can't reproduce it.

Anyways, enjoy the game, you may need to exit the Steam if it's not updating.
