Thank you :)
Right now I am working on weapon crafting and as you mention it, I'll add "swap weapons" button to make it easier. Probably tomorrow there is going to be a new build with new weapon system (the actual crafting is going to happen after that).
Yup, alone. Not decided on the price yet. I was thinking about $15-$20 but that still depends on a few important things. And with current world events the situation may change within the next few months.
