Small Bug Fixes

I made a couple of small adjustments to the game.

- Fixed Jumping - Sometimes the jump button wouldn't work due to the fact that, in the middle of my panic, added the jump detection on the FixedUpdate. Changed it to the normal Update, should work fine now.

- Main Music Pitch - There is a part in the game where the main music changes pitch. Everything work fine, but if you replayed the game after finishing it, the pitch wouldn't reset. It's fixed.

Also added a WEB version of this tweaked version of the game.
