HTML5 and minor bug fixes

Hello!

Due to the ongoing ratings of jam entries this is only a minor update consisting of bug fixes, this is to show the game in its submitted jam state whilst avoiding any misrepresentation of the work completed during the jam's time frame. Afterall the code for this game was originally written within the final 4 hours of the game jam!

New:

• HTML5 export of the game, with fullscreen switching.

Bug fixes:

• Vertical collision detection re-enabled to stop the player moving outside of the camera's view.
• Player now dies when falling into the water.
• Player changes back to idle state after dying.
