Number minigame in a nutshell: save before playing, play, get some numbers right, fail a stage, hit f12 to quit to main menu, watch unskippable intro credits, load save, rinse and repeat untill you clear all 4 stages. then save and do the whole thing again.
edit: OR you could just CE your tries in and give yourself 99 tries or something but i didnt do that because it got tedious to keep on editing it. which is probably ironic in my case since im constantly saving and loading for each try in the minigame i do?
