Yea thats the highest we got, we then tried to see if abandoning rooms would help us keep the important ones but every room seems to play an important part, which we really like. Our favourite misfortune was when we both got stuck in the enging room even though my friend was screaming at me not to come in, I though I could fix the leaks before it filled up but alas, I failed lol.
Had a good run, though due to tons of wires we could not get the leaks so rooms filled up blocking our avenue to get coal into the engine and fix the wheel. Turning the power off to get wires ended with us running out of speed so we needed it back on to pick up speed.
Somehow we are actually improving lel.
