This is very cool! I was just looking for something with better movement controls than Bitsy, and Whimsy's controls feel very good to use.
Do you have any plans to implement layers? I was testing using props to create visual effects and wanted to layer them in front of the player's sprite when the player walks through them, but didn't see a way to do it. [Edit: never mind, I found the foreground/background toggle! Didn't realize it was there until reading through the devlogs.]
