This is such a curious game. I love the art and music (the protagonist’s walking animation is particularly lovely), and I think I get the gist of what you were going for, but I fear that I am not smart enough to deduce how to get an actual win state.
I looped through the game’s stages a few times, but nothing stood out to me as an obvious clue on how to progress past the “Boss of the Future.” Perhaps I simply missed it.
Nonetheless, the platforming aspect is solid and I enjoyed the combat portions! Excellent work.
