It is sad no-one bothered to help (and it is an easy fix too), though you probably found the answer by now though I will tell you anyways just for the off-chance otherwise:
You can download the PC version to PC, copy the .HTML file to your phone (place it in a folder named something of your choice to the effects of "zeGames" or "- games" (whether you want it to be at the bottom or top of the alphabetical listing; that or use whatever folder you may have already in use). Then open your file directory icon ("My Files" or your cellphone's equivalent), navigate to the folder that you are storing the game at, then select it and to Open in Browser.
I have used Brave, Chrome, and I believe Firefox to open it and did so without issue.
