Nice NES vibes! Unfortunately I don't think the music is set to loop (?) so it had finished before I actually started the game, and I couldn't hear any sound effects. But I enjoyed collecting the little power-ups and exploring the map. I think the "bad superpower" is mostly held up by the unstoppable jump as it stands, since most other power-ups just felt useful. But I'd love to see what you could do with this given more time to accomplish some of your extra scope. Great foundation for sure.
