I was pretty proud of my Game of Life & Wireworld implementations for the terminal, with half-character resolution o.o;
Guess I'll have to up my game and start work on Twin Cobra and Dune ][ clones.. now that I've seen it's possible..
Using sprites is clever :-) then I guess that's how these older games worked too.
the sprites aren't all the same size or as good as they could be but already spent too much $$ on sprites.
the sprites are just passed through algorithms that optimize for what text characters at different aspects would make them look good.
