Improved keyboard bindings for gamepad haters
several levels refined to make sure you learn a game mechanic rather than skipping around it
improved subtitles - all narration subtitled, better display, etc
narration now makes both music and FX get quiet so you can actually hear my PERLs** of wisdom.
re-made start of level 9 so that you can't get stuck
"improved" in-game feedback system, and now I'm advertising it so that everybody knows to begin the deluge of quick and easy feedback (gulp)
mazes have slightly more clear tells so that wandering randomly is purely optional
other things less easily described, or spoilers. Trust me. I'm not just making this list look longer by padding the number of changes with "other"
** would you like a list of other programming languages I know how to spell? let me know.
