I'm not 100% sure, but the jam may have asked to incorporate all three NES titles that were assigned. Regardless, I'm a fan of the layout and graphics, and the excellent use of Mega Man.
The start menu table of contents and the pre-gen stat blocks are all splendid. The map is clean and readable, and for the most part, I was able to identify the rooms from the descriptions easily. I have an idea how I might run the sliding floor tiles, though it's not immediately obvious to me. Fun thematic monsters, especially the Silent Guardians (a la the Weeping Angels). The distended giant snake is a great way to clue players in that it has one of the crystals.
We need a stat block for the Ancient Weapon so we can have a Kaiju Battle! Awesome work!
