Please reimplement the "Restart" button into your HTML game.
fore various Reasons like wanting to start a new game the only way to currently do this is to Close the Tab and then Restart by finding the File again on your Computer.
but the more Urgent reason to have the Restart button back is that sometimes when you Restart your Web Browser, some HTML Games might not Load Properly if there are many Script's involved, and using the "Restart" button is the Quickest and Easiest way to Flush the Messed up Script's and then loading the Save file, because fore some reason ONLY loading your Game is not Good enof if that happen...
this is an HTML Game Problem Not an Your Game Specific Problem, which is way i am asking if you can Reimplement the Restart Button fore convenience sake.
no i do hope you will have an Good day forward and am looking forward to where this game will go from here.
