I’m preparing some builds for casual portals now (which I’m technically not allowed to name because of the contracts). One of the requirements is that it use DirectX. 
32bit build worked without me needing to change anything at least ! I was only delivering 64bit to Steam but since it works I’ll begin to deliver 32bit too most likely as long as nothing breaks. Will be its own Steam depot and its own build/bundle step.
In the Library update something we tried to do is address people’s issues who left negative reviews on Steam while also making more content for the people who did like it. So far the result has been that none of the negative reviews have flipped to positive as far as I know, but several have updated. Most of the negative reviews also did originally mention they did not like the match2 mechanic and preferred the wheel up/down mechanic. So I think that is the fundamental issue still, and nothing we change in the game would flip those customer’s opinion on the game. So it’s a lesson to recognize issues like this and do what can be done to improve the game for people who would value the core mechanic. Other negative reviews are still useful for highlighting shortfalls, but improving on and reinforcing what people like who already value the product is a much better focus. Instead for those who prefer a different core mechanic they will be served with future products made more for them.
