no save? what. the crawl of the game requires it to be played for an extended period of time. i had gotten to the 10q upgrades, now nothing.
so, won't play without that, and.. i'd add a requirement of formatting the numbers. consistency! you use shortened number references in shop, but you have non-fixed width fonts in score display, obc/obc, and in upgrades. fixed-width, comma format AND allow for optional shortening by name or scientific notation.
