Congrats, Frozenskin! Just getting anything
done and released is a big deal. :)
I'm not sure why Chrome is convinced your zip is malicious -- like you said, the .exe file you've got in there matches the verge.exe in the standard download exactly. I've downloaded it and will give it a play through when I get some time (maybe not before this weekend sadly :( ) but in the meantime, I uploaded your game to my own webspace...
It still gives the standard "this isn't commonly downloaded" warning but at least it doesn't say that it is actively malicious. The only thing I can think of is maybe Mediafire is the problem?
Anyway, feel free to use the link to my upload of it if you'd rather. The warnings are a little less scary, and I believe we can ask Google to just directly check to see if the warning can be removed (https://productforums.google.com/forum/#!topic/webmasters/kaJ0cSw91Ng

If you don't
want me to host a copy for you, that's fine too! Just let me know. Not trying to steal it, just seeing if an alternative domain did better. :)
