ascii hero (jump'n'run)
Posted: Sun Sep 26, 2010 6:24 pm
this weekend i wondered if i could make something jump'n'run-like to play within the console/terminal, and what i hacked togehter is quite funny to look at, so i will share it here.
i'm making use of the pc-speaker (beep), so if you have one and your boss is around then better set the constant '#no_sound' to 1.
for keys see the comments in the beginning of the code.
