The art, music and concept of this game made me feel like I was playing an actual NES game. Kind of reminds me of this game I saw called Tower of Heaven.I loved how you nailed these ideas together! Sadly though, the jumping was really unresponsive and it was hard to jump over some of the platforms. Still, I managed to finish the game because I love the feel for NES games. Also, it would of been nice to have a volume adjuster as well as the SFX was kind of loud and it drowned out the music a bit, which I was really enjoying. Also, the SFX keeps playing when I spam spacebar.
Overall, amazing game entry you got here!
