I would love to do that I just don't know how
I already gave the solution in my post. Please read:
Lastly, when played in Bitsy Unlocked or Bitsy, the Sprites are all messed-up (not at all how they look in-game when playing from the .html).
(If either of you still don't understand, it means: All you do to play in your browser is click the .html that you download. And if you want to edit it, you simply open Bitsy or Bitsy Unlocked and click the: Game -tab, then: Save -> .html: Load Game). EDIT: As per Tahoma255's revelation, TBC was made in Bitsy HD, so only Tahoma255 can make any actual game edits in that.
