I played your entry on stream if you wanna see the video below! The art is on point for everything here. And not just individual sprites but the direction of stuff like the hanging skeleton, and how it really is a clue to where the key is. I didn't get too far, but did enjoy the overall feel of this very much. The sound was a bit jarring, I found myself adjusting my volume, but I guess that's very appropriate for the fictional 1991 GB title that it is! If you get a chance check out my entry, too!
