Thank you for your feedback.
Unfortunately, at the moment this is not our best version of the game and it will be greatly improved for the next update. However, we do not know what exactly can be done with the control buttons, I am very used to the current one, but many people offer different control options every time.
As for the chains, this mechanics is completely unbalanced. In addition, the new update will have a very different combat system, so we will already start from it
