Regarding how the player will jump between walls, it’ll likely be a combination of a 0 gravity Rigidbody and coding the script. When the player jumps, it’ll apply a force away from the surface they are on, and when the player touches the opposite surface, it will reorient itself (possibly using normals?) to “stand” in the surface.
In scenarios where gravity is required (which might not necessarily even be used in the game), I’ll likely build a custom script to allow gravity in any direction, although it’d really only be used in the 4 cardinal directions.
I want to try and avoid Rigidbody’s built in Gravity system, as it only works vertically, whereas the solution I implement should support vertical and horizontal gravity.
As for other mechanics, I’ve definitely got a few in mind that could definitely lead to some interesting puzzles, such as the more typical electricity and moving platforms, as well as some strange mechanics too, like player death mechanics.
Unfortunately, I’ve not got many details to share on how these will be fleshed out, but I don’t imagine these’ll be too difficult to implement.
