TL;DROne word: HOVER BOOTS! (... ok, 2 words)
What ?OK, one issue I have often when working on belts, especially in my main bus, I get moved around uncontrollably by the belts. This can be frustrating, especially when on concrete or when using exoskeletons since the speed boost combined with the unexpected movement leads me to place belts and items in places that I didn't intend to.
Hover boots would be a an item that could be inserted into armor (maybe 2x2) that would let you "hover" over any belts and you would only move when you use the movement keys. Since you are slightly off the ground, the belts wouldn't move you.
I would suggest a cost of 100 blue chips, or something expensive. Maybe it could be an upgrade to an exoskeleton.
Why ?WHY do you think it increases the value of Factorio as a game?
Less frustration? more control? and that name ... HOVER BOOTS, MAN!
Thanks for your time
