current progress is set 2, day 4.
background visible, added a background image
massive updates including changes to add sprite positional change
functionality.
hived the keylistener stuff out to its own class, worked on getting duck
to ACTUALLY stop movement. Currently it stops x motion in progress when
player presses duck, but doesn't prevent x motion or change sprites if
player STARTS x motion while ducking. Deciding whether to handle that
with sprite transition or all out stoppage.
fixed a background scroll error related to a math problem. also a few
patches back changed space and up button functionality. space is a
single, controlled jump. up is an infinite jump added to amuse gf who
giggles while compulsively pressing it.
major refactoring
