Hi, I'm getting a virus warning when I download this game and try to extract the ZIP file. Windows Defender tells me that Script/Wactac.H!ml is a Trojan and then it deletes the folder after a few seconds. Even just leaving the file after I download it auto deletes it. 

I'm unable to play the game in the browser, because the resolution doesn't work properly and the game crops on my display. 

I'm so sorry for your inconvenience, have you try clicking on "More Info" and then click on "Run Anyway" after the Windows Defender warning appeared? In my case, this will solve the problem.
And if you want to play this game on the browser, try clicking a blue fullscreen button at the bottom right of the game screen after you clicked the "Run game" button, this way will make the game enter a fullscreen mode and you can play the game normally.
