Thanks for the share, btw, I was wondering if whether you do any freelance (paid) development?

Barbosik commented 5 years ago

it's just a hobby. I'm playing it with a custom client and don't get any profit from it. It's not a problem to share it. But it can be used by stupid mass botters to develop a new bots. I don't want to help stupid mass-botters, so this is the reason why I didn't shared it.

SuperOP535 commented 5 years ago

But you shared it? Or did you mean the client 🤔

Barbosik commented 5 years ago

I mean the client
