Thanks for your questions!
We're CHAINWISE from Berlin. We've been in the space for quite a while, but not so active on Steem (although we love Steem, just a matter of focus).
Head over to our website to check our founding team, or join the Discord if you want to get in touch with the @chainclash team directly. There will also be content directly from the team on the social channels and, again, Discord.
The game is built on EOS because that seemed like the best option for a game with its on-chain features, the scalability and the adoption in gaming. So far, we're quite happy with that choice.
We are, however, bullish on Steem, too, but for different types of applications. Happy to discuss more in-depth about this (maybe we'll also crank out a separate post on this).
