I think it would be better to think a few quest through and possibly revise them... Math Test 3 requires savant-level skills, while attempts at High / Low 5 will succeed, on average and following the best strategy, once in *two years* if you play high/low *8 hours a day weekends included*.
I first discovered this game through Weebl's website and I absolutely loved it at first sight, though it is frustratingly difficult. The minimalistic graphic style and the Radiohead-esque music are captivating and the game mechanics are as elegant and cunning as they are simple. Kudos.
