Hello! To clarify, Barotrauma's normal price on Steam has never been raised, or lowered; it has stayed exactly the same the whole time we have been available for purchase, expressly to avoid posts like this one :) As for what kinds of prices you may have seen at key resellers, I will not comment on, because we have no control over that.
