This scam market-place does not pay its developers. They take your money, pirate the source-codes and assets, claim to advertise to market for you, and give you nothing.

"We are small team, who are mostly working on projects that could help
for other developers to create their own projects. Before two months,
we've received a letter where marketplace owners(Game Gorillaz) said
that the payments will be delayed due to some kind of country problems.
We said it is alright and we will wait for a respond, but after two
months we still didn't got any answers from them. They said that all
payments will be credited to developers accounts until 15th of March,
but we haven't got any money. Now we think that they just appropriated
our orders and tried to delay all our requests. We think that we're not
alone and there is way more developers who didn't get they payments. So
we would like to share this message and let everybody know that not
every marketplace is good for developers who want to earn some extra
money. Still, we tried to contact owners, but we didn't get any
response. We have all orders with all customers who bought our projects.
So, we would like to know is there any institutions which could help us
to solve this problem, because were are thinking that there are tons of
developers who are waiting their payments and can't get any response
from owners."
