Amazing! I wish there was more but appreciate the effort that went into every little detail. It perfectly fits the NES theme and is really well polished. I like that you incorporated the short length into the story at the end - all very well thought out and a perfect entry for a game jam! Sprites are fantastic and I loved the hat throwing mechanic and how you can knock enemies over before jumping on them to finish them off, and using them as bounce pads to get to higher areas too!
It really reminded me of Super Mario Bros. 3. Especially the run animation and the little 'ba donk' drum sample that featured in the music. That was a nice touch!
Great job!
