Coded by old-school C64 veterans Chris Shrigley and Terry Lloyd no less.
Though it does make one wonder whether two dudes who wrote a string of legendary C64 games and then had entire other careers after that dusted off their knowledge of 6502 assembly and VIC-II timings and wrote another game, and if they did so, whether they found it harder going after all these decades. (The other option — that after decades of not working that close to the machine, they vibe-coded it — would be depressing.)
