It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).
We suggest you upgrade newer and better browser like: Chrome, Firefox, Internet Explorer or Opera

Starting the game results in a error message, something to the effect of:

blah blah... api-ms-win-downlevel-kernal32-12-1-0.dll is missing. Try reinstalling

Dismissing the message will allow the game to finally start.

This apparently has something to do with the UE4 Editor. No idea why a UE4 Editor error is happening or what effect this may have on game play on down the line.
