While looking around on youtube I found this: https://www.youtube.com/watch?v=cbkl2N87DHo
It was made using solarus and it looks as if it is a short game but completed. Does anyone know anything more about this??
From what I've seen this is a big Zelda-1 like labyrinth
Looks like it has been made by ZeldoRetro
Reminds me of Darunia's Cavern from Parallel Worlds as well
