andy I'm interested in others' opinion: is that extreme? I think it's probably near the top end of hard.
ColonelFazackerley Glad I made a challenging level. Your solution fails when I view it. I have tried a few browsers.
ColonelFazackerley win 10 chrome, win 10 firefox, win 10 edge, fedora chrome: fails fedora firefox: i see you win! fedora konqueror: the game does not render at all. is this the result of subtle differences in client side floating point calcs?
andy ColonelFazackerley I assume it is about floating-point, which is super-weird because JS is supposed to follow the international standard IEEE.
