We have the same problem: https://purefunlab.itch.io/bagman.
Our game was published 8 days ago and it's not listed anywhere.
We've also contacted supported a week ago and didn't get any response.

Can someone please help us?

Hi everyone!

After a long period of hard work and excitement, it's finally live :-)
We are excited to release our first game:

Bagman: Cash or Clash!

You need to survive high-speed pursuits in this survival action game and collect protection money for your bosses.
There are several locations, cool vehicles, and powerful weapons, ready to be unlocked.

You can buy the full version for Windows and Mac or try our playable web demo on our itch.io page.

With your support, we hope to bring it to other consoles and platforms soon.

We decided to give a limited amount of free download keys to Itch.io community members! Leave a comment to get one.

Your comments/suggestions are more than welcome. 

Thanks :-)
