Hi Teekayeh! Thank you for being interested in the game! I know some people who have downloaded it since it launched here just fine, but just to be sure I double-checked and gave it a try and it successfully completed the download for me. It seems Windows Defender doesn't like it much that it's an .exe though and needs to be told to run it anyway. I don't know if that's the problem, like is it some kind of antivirus thing or something else on your end? I really don't know.
My suggestion: Try to download it in another browser first, if possible. Failing that, try it from another device. And if that's not a choice, I'll just get it to you some other way :) Let me know!
