I've always thought about a ton of games I'd love to someday be able to create, but my inability to manage learning a code cripples my progress. :(
I'd love to design a Metroidvania game with Skuld from AMG... Leave me alone, she's been my favorite fictional character for about ten years, now. Anyhoo, I'd love to have lots of incredibly challenging rooms with the "HAHA" traps that IWBTG presents and offers, but allow a few different ways of working around it. Sorta like a Rubik's Cube, where the end goal is shared, but many methods and paths to reaching it, where each method and path requires a different method and path to continue down that method and path.
