Scamper: bloodbath with an extension at the beginning instead of the end
Boobawamba memory gimmic (only the darkness) with blue pad mirror portal (a lot) transition (looks cool imo it’s from a map pack level) any you control swing and not ship
Concentration: Platformer Dungeon-like level where you have to get keys to open a door at the beginning (retracting) with a Bossfight behind
Brainstorming: prompt is apple, idea is a Bossfight level apple themed where you fight an apple which is shooting kernels and to defeat him you have to get speedportals to catch up to him and eat him (starting at slow —> 4x speed
Ramsey Method: level where you travel through many galaxies with star constellations in the background with you flying into them (ship or swing) and then transitioning to a new constellation with the end being flying down to earth (https://en.wikipedia.org/wiki/Mira, https://en.wikipedia.org/wiki/Star, https://en.wikipedia.org/wiki/Star_cluster)
Brainstorming was easiest for me with the best idea of them, but with Scamper I could get ideas faster.
