Thank you! You're right, I plan to fix these issues in the nearest future
One note about right click - mobile doesn't support it, and even long tap frustrates much more than current game menu. I would like to introduce option (m.b. determined automagically) to enable right-click. But i need to figure out how to support some browsers with feature 'mouse gestures' which conflicts with right click (it usually throws you away from page if you use LMB and RMB at the same time).
