Hey this was a really cute and wholesome little entry! I loved the artwork, the retro vibes, the simplicity and everything about it really. It wasn't overly complicated, it wasn't another dice game, it wasn't made with AI, i genuinely think you did a great job with this one.
In terms of feedback for improvement, I would consider making sure the music loops correctly because it suddenly cuts and restarts which feels a little jarring. I loved the multiple doorways idea (the whole thing gives Amstrad x C.S Lewis / magicians nephew vibes) though it would be nice to see maybe some different themes for each room, even if just a different colour scheme and maybe a few more decorative environmental objects to spice it up / make each room memorable.
For a one person team you did especially well! good work
