This was fun! Faithful to the NES, but with a few modern design conveniences that don't upset the balance too much. The variety in the game is fantastic, especially given the timelines you had to work with. Unfortunately wasn't able to finish it, since I got softlocked into a wall when passing through zones about 1.5 hours into my playthrough. (A quick glance at my inventory suggests I may have been just two items away.) This came after another instance where I nearly softlocked when I approached a zone transition from the water side and couldn't progress without the ability to open yellow doors, and couldn't regress without a dash jump (which I was unaware was an option).
I could echo the desire to have somewhat faster movement, and more frequent save points (I hadn't realized there *were* save points until my second attempt), but my "biggest" complaint is about how you're cheating in more simultaneous colors than the NES could show ... so given that, it seems fair to give you your well-deserved kudos.
