I enjoy playing this game, it gives me indescribable feelings of excitement. But do you think you could try and port it over to Android? It might be hard to incorporate all of the mechanics, but it could be possible.
The game seems too heavy for Smartphones to run it without a lot of time and effort wich could be spent instead on new content and faster bug fixes. Also the controls would be pretty hard to implement
I know, but on the steam page, it has "Partial Controller Support". Also the minimum specs requires 2 GB ram, so besides all of the difficult sh*t, I think he can do it. (At least get it on GeForce Now)
