New update 0.3.1:

• Added custom icon to the demo;
• Made an early section of the main game easier;
• Added keyboard support for clickable links;
• Improved detection of low ceilings to stop parachute deploy;
• Improved background for challenge area;
• Improved visuals for secret areas;
• Made practice beam render over the player and secret areas;
• Fixed a visuals bug with moving clouds of main menu's background.

Everything I wanted to add to the demo is done, at least for now: if I ever update the demo sooner than expected, it will be to change the level design, so give me a reason to do it by giving feedback!
