First of all, welcome! Secondly, és brasileiro? 
It’s cool to see people pushing the limits of CS. I wrote a python script to generate an inventory system in CS for me.
I don’t understand your maze though. What do the commas and the hashtags stand for?
Also, you should consider that the game would run on different screen sizes, so this might phunk your maze. Besides the typeface.
Edit:
It just occurred to me that instead of common characters, you could use unicode characters with predefined lengths like:
Unicode 2588 (black block): █
Unicode 2001 (empty char). This is not the same as simple whitespace! Unfortunately, it seems Discourse converts empty characters into whitespace. So it won’t show here.
You can discuss DashingDon in its own thread:
And to contribute with features I think you would have to talk with @dashingdon.
