Hi, creator of MAP04 here.
Thank you for reviewing my very very modest map, that's my first speedmap and my second map ever so I wasn't that used to the editor compared to the senior mappers, that explains the shortness of it, but I tried to make it at least a bit challenging, I was going for "Plutonia on UV difficulty". (Meant it to be played on UV)
I calculated just the right amount of ammo for people to survive and even then, @WH-Wilou84 and co told me it wasn't enough! So I added some.
I'm sorry about the two fake exits, now that I think about it, I should have got rid of the second EXIT panel.
About the arch-vile, I thought I had made the stairs impossible to climb for monsters, seems like I forgot to modify some linedefs there, again, sorry.
Still, I'm glad it's not so bad according to you all, thank you.
