This is a very basic scene creator - not particularly much to do within it, and not much content either.
The tutorial was pretty fun to watch - Scratch and Knave had pretty good chemistry with each other IMO.
Its also an absolute *treasure trove* of medals. If you're looking to get either of the secret medals, here's how:
For "Treasure Oh Treasure!", swap through backgrounds until you find a purple-coloured cave. Then, click the treasure chest.
For "Enter the Phoenix!", swap either character to Afterburn (use its associated medal for reference), then click the edge of its (small) wings.
Getting the rest of the medals isn't hard, either - just swap either character to a Miscrit whose medal you haven't earned yet, then wait one minute. Rinse and repeat until you've gotten everything.
