Alright, I just had to chime in here (and bump this to the top again). This is an amazing piece of work. The full version on itch.io is a must play. Not only is this an amazing technical achievement, but it's actually a good game. The maps are intricate, twisting, and keep adding elements to keep thing interesting as you re-traverse the maps. And you even gave the Cyberdemon a minigun so he's not so easy to humiliate. Though he is more than a little spongie on higher difficulties. First time I played was on "hurt me plenty" and I wasn't sure I was actually damaging him until he suddenly died. Seemed to take way too long.
It should be mentioned, this isn't Doom. First of all, this isn't running the WADs from Doom, but there's also a lot of little differences in how much health pickups heal, the damage done by certain weapons, and other things. I mention this because in the "Pico-8 plays Doom" celebration, I think it should be said that, "No, no it doesn't." This ain't Doom. But it ain't bad.
I want more.
More episodes, more maps, new monsters (even if others have to be dropped to do it), and a BFG in there somewhere.
I love POOM.

thanks for the praise!
Poom 2 won’t happen unless I can find an artist to expand the universe \o/
