Great game! I played to the end and loved the art, music, and sound effects. The boss presentation and style were great throwbacks and very fun, and the final cutscene was perfect. I even enjoyed the occasional lag because it truly felt like an NES/Famicom-era game. From your "Post Jam Note," I can see that you're already aware of the few issues I encountered during gameplay. The one point I would add is that it took me a while to figure out that *holding* the jump button when encountering a spring-board, rather than timing the press with some particular part of the spring motion, was the way to use them. I agree with another commenter that I would have enjoyed a higher level of difficulty over time (like the enjoyably frustrating 80s/90s games), though I realize that varies by player taste. Great work!!
