Okay, after about 21 years of not doing any 6502/C64 coding, I came back in 2013 to have a dabble. Eventually, I made this homage to Flappy Bird in 2014. This was coded using Endurions C64 Studio IDE. Its a bit rough around the edges, with some glitchy sprites on the pipes, but its playable enough and is a tricky highscore chaser. I never bothered to put on a front end. Its straight in with the game with this one. There are "cracked" versions available with a highscore saver added that will save...
