That'd be a 89.5% speedrun. Anyway, I was casual speedrunning 1-50 while watching SGDQ when I had a thought if I could speedrun the steam achievements. I looked and there's an obvious divide between which achievements are worth speedrunning and what not to. The 2 achievements are, of course, Step On 5k Bombs, and Mark 50k Bombs.

A lot of achievements are gotten automatically, but you'd have to keep track of hearts and do a few side things. Would this be too minimal difference from 1-50?
