Im sure they have plenty to show but they are going to keep it to themselves until its finished or at least complete and stable.
Some people, like me don't mind posting stuff about the work we are doing and even the bugs and stuff.
https://i.gyazo.com/c580483896f42f6defe84705d4440bad.png(had a looping function (0.2s) that i forgot to clear and the widget i removed was not being removed until the next garbage collection so it spammed false and allowed the player to spam new widgets
took about 2 hours to find why)
While others would like to have their work looking nice and presentable before they show it off.
I'm guessing that XMoon would like to have their work complete before they show it off.
Like the new lighting system they implemented it was shown off after it was finished(it looks so pretty i wanna play with it).
XMoon is not a AAA game company and as such they don't have deadlines which means they can take their time and implement all the things they want and make sure its bug fre.. less bugs.
This also means it takes longer but the quality will be better then a crunch mode rushed game.
Im just happy XPA decided to come and say hello.
