Hey Shdwlynx, I'm so glad you're enjoying it and want to see more come of it. Multiplayer is definitely one of the major and desired pillars I'd like to implement into the game (along with more holes and different courses).
As of right now, I'm working on this passion project on the side while also pursuing opportunities for my career, since it's not making revenue yet. My ultimate goal would be to pitch the idea to Oculus and see what they think about putting it on their platform, and then maybe I could get funding for development.
I am trying to keep a track record of releasing an update for the game every month, so keep an eye out for those and I will have more to share as time goes on. I appreciate your support!
