After playing this game for a few hours, I honestly believe you have the chance to make Fear The Wolves into something special. However I think the game should certainly remain in this free beta stage for the time being until it is running a lot smoother. Charging for early access in this state may cause a bitter taste with your fans and future players. Roll out a far more polished game into early access and this should grow and grow. just don't rush it out !
As for an idea I had for a feature in the finished game, I would like to see challenges we can complete to unlock certain cosmetics like clothes and weapon skins. This would be a nice change of pace from all the loot boxes and cosmetic stores we see in games now.
Thanks for reading !
