0.5.2: Demo patch #2

0.5.2 patch notes:

• Course screens now display your previous lap's time for a few seconds on completion

• Springs no longer prevent the use of your midair jump for anywhere near as long, and double-jumping while you have upwards spring momentum will maintain a portion of the prior momentum (TL:DR it feels better)

• coloured spikes now target the player's hurtbox, as opposed to its hitbox. They should feel a lot more generous.

• auto-hides your cursor in fullscreen mode when no menu is open

• the box that previously turned the lights off now pulls up a "demo end" screen, the same one at the real end of the demo (course 4). It doesnt say it does this, it just does.

• minor reductions to the scaling factor of the upgrades in coruse 2

• The traversal section between 3 and 4 now blocks players from skipping it when coming from the left (though, it's still possible if you wall-dash or whatever we're calling that tech)

• The death animation when players hit spikes should always be consistent now.
