My Macbook Pro 2012 High Sierra OSX Downloadable Tanki Online HTML5 Client for MAC works as described!
BUT the MacbookPro 2015 & later version in Under System Preferences ICON APP "Security and Privacy must " unlocked" then only chooses [ ] is apple developers or [√] Apple Developers and "Identifiled Developers" this No longer allows this option "Open anyway " using in OSX MoJave - Catalina OSX posted October 23 2020. Used to use Flash(and client) well in Safari Browser most of the time and FireFox browser now will not load completely.
Hope you can update resolve to accommodate both issues Safari FF Browser not fully loading and Tanki HTML5 Client for later Macs.
I Love this game!
