hu just a bit ago I was looking into the same thing.
Here is a thumbnail y'all can use if you chose to add this to your non-steam games library. Like I did. For some ungodly reason.
I quite like the art style and map design you did with this game, the lack of unique weapons and mobs makes it feels like I'm playing a reskin of doom. (I mean I kinda am ) Good work all around though.
