Hello there and thank you for your comment! :D
We are more than happy to share you some tips, as we always want to encourage & help all types of developers to reach their goals. We enjoy crafting our games as a hobby in our free time and that's why we don't pay any money to promote our games. Instead, we count on our wonderful community to play our games and share their experiences themselves.
Here's a comment we posted on your page, that goes into more detail. Thank you once more and have a great day! :D
