Wow! I can't believe how much you were able to fit into a two week game jam! This game looks, sounds and plays just like a real NES game. I'm impressed with how strict you were with the NES restrictions too and it really pays off. Castlevania on the NES is one of my all time favourites so this was hitting all the right spots for me. The tilesets are incredible with loads of variation and the sprite work is amazing too.
Really good job!
