Demo 1.02 Released for Windows

Fixed some silly bugs.

• Hopefully no longer possible for Muffin to clip into, and thus get stuck in, walls
• Pressing the `Jump` button to unpause the game with the pogo equipped will no longer make Muffin jump
• Pressing `Esc/Start/etc.` to start the game no longer immediately pauses it
• Stretching/squishing the window will no longer let you see like 20 screens in either direction

Also, removed the Linux download, because it was confirmed not to work. Still lookin' into that. Still not sure if the Mac version works.
