Demo v5 - Gamepad support!

Hello, Braincells!

Remember like... yesterday? When I said I was not going to do further demo releases? That was a lie!

But I have a good reason. As it turns out, adding full gamepad support was not hard at all! Controls:

• Left joystick to move
• L2 to dash
• L1 and R1 to pass the braincell

It was so easy and it seems to be working, so I felt another update was in order.

There are probably going to be some gamepads that don't work, but aside from ordering a bunch of them and manually mapping out their controls, there isn't much I can do about that. Most name-brand USB controllers should work.

Anyway, now I can go back to level design.

Unless I get distracted again.
