I love the movement mechanics. They remind me quite a bit of Mega Man X and Zero! I love chaining dashes together and especially dash jumping! Only feedback I have is that it seems like the music doesn't follow the NES limitations accurately, as there seems to be FM synthesis in the Music, something the Genesis was capable of, but not the NES (it has 2 pulse channels, a triangle channel, a noise channel and a DPCM sample channel.) Slashing enemies feels great, and thanks to the forgiving hitboxes and great movement, you can kill most weaker enemies without breaking the pace. So satisfying!
Thanks! Mega Man X/Zero's flow of chaining dashes and blasting through weak enemies is exactly what I was going for. And you're right! I am a complete newbie to making music in general, so I didn't try to be NES-accurate with it. I used a handful of Genesis-style instruments to make it easier on myself.
