VERSION NES
Make the port has been my endeavor. I contacted the team and they seem to like the idea. By now I was trying to make a demo of the first level.
Graphics and map are already done, and now I'm developing control the player. It operates a door, and little else.

I pass a small alpha so you can see progress. In this alpha you can switch screens by pressing SELECT or START: UPDATE 10/06/2017
The Barbarian makes it simple to jump and climb: when we approached a skull and press the A button, the barbarian climb.
