Changes:

Added some more menu polish: fading menus, button offsets and such.

Supposedly fixed a crash related to certain projectiles colliding with other projectiles.

The "Sticky Ledge Grab" option is now on by default. ie: left/right directional keys no longer let go off ledge grabbing.

Updated a few room layouts.

Tweaked the demo boss: reduced health slightly, increased fly enemy item drop chance, reworked the red blob attack, improved tentacle visuals a tiny bit, the boss fight now also triggers after a certain time has passed.

Supposedly fixed an issue causing half the HUD and boss health bars to be invisible.

Tweaked player ledge grab jumping physics a bit, you now get a speed boost allowing you to jump further.
