I'm working on it :) It's more like an Alpha Test, If you'd like I can send you over what I have so far but it may not be very exciting. The first Gym will still probably give you at least 2 hours of gameplay or so. It's up to you!
I saw your thread, and I just wanted to let you know, that if you want people to use your maps, you'd have to give them the game project file, not the game itself. Anyways, I posted on your thread, so if you want me in on your project, just message me here, or a private message.
