It does not take a week to port a 2D game to VR, it takes a whole lot longer.
Also, the person who made SL VR is working on this game. We have all been working on it for the last 9 or so months; taking games takes time, and I'm only 17. And I just recently made the game dowloadable in the Discord server for all the impatient people/so it's easier for me to test multiplayer stuff with the community and faster.
