Compatibility Upgrade

Hey everyone! I just made a few quick changes. I upgraded a lot of behind the scenes stuff to comply with new standards in JavaScript coding.

I also tweaked the UI in the game. I made the menus easier to navigate, lowered the time it takes to move from screen to screen, and reworked some of the sounds in the game. Music changes faster as you climb the wall, and portals will spawn in more random locations. Story mode will no longer give you a "ch 2 coming soon" message, as I have decided against continuing the story in this game. The story does continue, but I recently decided I want to encourage users to look for the other parts of the story in my other works. I am currently trying to polish off all my public projects right now, so expect a few more updates like this.
