If all your seeing a screen with an X and some writing in Korean, you need to use a VPN because it says not available in your country. If you can actually see the screenshot, then at the bottom of the page is a long string of letters and numbers. You need to run that through a Base64 decoder (just google it), that'll give you a link to the download page. You need a password for it, which dovaper provided a few posts back. Yeah it definitely takes a few steps to get to.
For anyone wondering about how this compares to the original game
