I beat it in a 4-7 hour sit. It might have even been shorter!
I think it was this posted that inspired me to attempt speed running it, which meant testing out doing different methods and if bonuses will be beneficial in the long run. During doing this, I was noticing I wasn't have much time difference in the Sandy Bay bonus game with the first few power levels and engine (do to the constant stops...) triggering me to wonder why, so I made the power stats table. So all in all, thanks I guess for that oddly inspirational post.
