I ADORE the visuals here, and the game itself is very engaging and endearing. I will admit, it took me a bit to realize that the exits were non-euclidean, and so I was a bit confused when I was trying to backtrack but suddenly I'd be in new locations haha.
All in all, fantastic game, would love nothing more than to see your idea for a fully realized metroidvania of this come to fruition, and even if that doesn't happen, at least more stages of this would be great.
Definitely adding it to my collection:)
