Why don't you put this game on steam greenlight? When he will get out maybe you would sell it at like 10$ and toggle some P2W stuff :D And make the Steam version diffrent from this one :)
I play a lot this game and I have some suggestions:
1)Add some new CR wepons, like grenade lunchers 2) Add the medikit in the skill tree 3) Weapon testing area (I don't want to buy a weapon without know what it can do 4) The more chance to get GP or Skill Points in the roulett 5) A way to create your own game room 6) For largest maps run feature
+ If you agree
Alien physiology.
