I enjoyed playing this game, as I love platformers, and I appreciate that you integrated the tutorial into the gameplay rather than overwhelming me with controls. The storytelling is excellent, and I'd love to see you finish and polish this game!
A minor critique is an inconsistency in art style, but that's something that could be fixed after the jam if you continue working on it. Some other stretch goals could include adding a boss fight, more attacks, rewards, and trophies.
