A bit more work to do to get all the basics up and running again but I really think all the major head-scratchers are behind me. I know how to put things on screen, do math, play sounds, open menus, manage input, load efficiently, control collision, alter objects, change text, swap images, and animate sprites. Getting into the groove of things now, and the rest is a matter of Find/Replace and Copy/Paste.
I just can't wait to have a basic functioning world to explore.
