Hi since the new version was set up a few weeks ago, the control keys have changed , for example, 'a' is no longer a pass key for me... and the new keys are unplayable , is there some option to set the keys? am I the only one in such situation? please help

You can change your controls in Profile < settings... You can switch them back or adjust them to your needs. One of the features of the new update which I personally appreciate very much
