-- Experimental minimal terminal rogue-like game in Ada programming language. I used to write a lot of Ada programs some time ago, then went in full C and assembly mode, and came
|
|
-- back to Ada, but realized that I keep my folders messy... Since it's bothersome to find my old Ada projects and share them here, I decided that the most easy thing to do is to
|
|
-- write a new program in Ada, a tiny game. Work in progress, it's messy and ugly for now...
