Lack of ideas and time have been issues recently so I won't take part in the contest this time. Sorry for the inconvenience.
Hi,
I like it so far, the idea of having puzzles including powerups was also something I've exploited in my Banana Fort level, because it's not everyday I have powerup extension baserom in my hands.
I've done a whole section built for Catsuit Mario.
Your screenshots seem simple atm, but well-thought. I don't know how to fix Roto Disc though, did you try to set this GFX bypass sprite tileset to castle?
Don't forget the maximum number of screens limitation (if I remember well, it's 24).
Thanks for showcasing :>
