About that level design thing
So instead of doing something playable, I just went with more graphics and “finished” the main menu, the vertical lobby and the horizontal lobby. Since it’s an open area but you only walk in one axis, the “indoor” parts will be more narrow.

main menu, with a button to choose to walk up/down and a button to walk left/right. title and credits button later

left/right path

up/down path
Probably changing the crystal in the menu with something similar to a flower, since the “bridges” endend up looking like petals.
