A rather neat little set of minigames, although I have a few notes:
It seems the 'par time' for system 1 is far too short, I'd never managed to even guess the simple ones before taking damage
Might be best to force the first six failures to go 'in order' just to show off and let the player see each of the minigames, as it was I didn't get sanitation until the difficulty started to ramp up
But even with those, certainly neat!
