I saw your api page z-pay.io/api and noticed it wasn't available if you guys are planning to have an api for the service in the future that would be great. When looking at your telegram channel as well I would recommend also adding the ability to join the chat group as well as the announcement channel.
After having the received the Ethereum to test the game here my review: When I started the game my metamask quickly prompted me to connect to the site and my eth balance was now connected to the site balance. I was able to purchase "pixels" on a board for roughly 0.005 per pixel. I was playing with some other testers, it was quite fun to play didn't manage to win anything while playing though and just used up all my 0.1 eth balance.
Thanks for sharing more about why you didn't want to get the license. I have personally played some eth on the site and have withdrew 1+ eth successfully within seconds. I would recommend you guys get your seeding even set up pretty quickly and that would be perfect
