I remember seeing something about this on Reddit. That was you, right? I'm glad to see you got your entry submitted and ready for players. I'm not an authority on group RPGs so I can't comment much there, but I like the look of everything. Ancient and just the right amount of creepy but legible.
On the game page, I'd suggest having the first sentence be something like, "In Demonomachy, you are..." etc.
Only because - the title of the game in the banner is gruesome and evokes the feeling of a bloody and gritty demon war - but is also easy to mis-read. The "oozing" bits blend together with some of the other oozing and letters so if I hadn't gotten there through here I would have had to spend a bit of time figuring out what the game is called. The subtext under it is fine, though.
