Version A_01

+ Wall Climb: if you wall run over the top of a wall, you'll move onto
the wall
* Crouching while against a wall will now allow you to pass through
newly open spaces
* Sliding off the bottom of a left wall will now properly update your
wallslide status
* Releasing crouch while underneath a platform will no longer cause the
character to spasm
* Jumping while crouching underneath a platform will no longer allow you
to pass through the platform
* The character is now 32x32, and his graphic has been resized to match
* Gravity has been tweaked - you now spend less time in the air for the
same jump height
