I speedrun monkey island 1 and 2, one thing the community always try to do is performing actions while walking, I noticed this doesn't happen in deponia speedruns (from what I saw), so I opened deponia doomsday and tried, I saw that rufus stops if you open the inventory, but if you click a destination right before opening the inventory he continues to walk, I don't know if this works only in doomsday or if it works in other games of the series, but it might be really useful
