I was contacted by the developers of the game and offered to invest in their project. I do not know much about games, so I ask for your advice. https://brick-worlds.com
Is this developer perhaps a user on OCT? Perhaps someone who asked you to contact them via Skype or something?
And, I mean seriously. This "brick worlds" which I feel I've heard of before, is blatantly infringing on the LEGO Group's intellectual property. If you're willing to invest in a company that's about to get sued then go ahead. Seems like some weird crypto scam too.
