Hi! We're currently creating a puzzle platformer which ought to play with a swap between a 2D side-perspective and a 2D top-down-perspective.
We've got a very rough first prototype (https://noqlu.itch.io/between-worlds) to test out the concept. We like it so far, but are kind of stuck at how to translate the side-view to the top-down view.

As of right now, most of the Level structure stays the same when swapping views, only the way the character controls and the existence of gravity changes:
- side view: gravity exists, movement to the left and right, as well as jumping
- top view: no gravity, free movement in all four directions

We've looked a bit into what differentiates those two perspectives (as in how obstacles work, whats only possible in each…) but we weren't really able to make much out of it as far as gameplay goes.
Apart from covering heights in top down, the only thing we came up with so far, is showing things in top down which are hidden in side view, but I don't know if that is such a nice puzzle mechanic to be honest.

This is why I am writing this: We're looking for any ideas you might have in how to use the individual strengths of both perspectives to create puzzles that play with the concept of being in >exactly one of the views< or >swapping between them<, as well as any ideas for objects we may could add into our prototype.

Thanks a lot in advance :)
