I just played the Demo! I really like what I see!
I was surprised that Latex Boy was not the strongest character. (I should maybe test more, but it seems like Scot Bun is the strongest?)
There is a part right before the Baron Fight where the Mancubi are stuck in the wall and can't do anything.
The lift near the Supercharge Secret can leave without the player and it takes a while for it to come back down. Also, it is activated by a linedef instead of a switch, so some people might stand on it waiting for it to never go up.
I was really happy that you made a custom map for this! It looks quite good! Though, the textures on the walls could use some work. And by that, I mean just better use of the proper textures and maybe some definition in the walls? I am bad at explaining that.
Like I said, the Scot Bun is easily the strongest character. He is fast, has a fast punch that is even better with Berserk, and has a great weapon that he always has.
It seems the other characters do not benefit from Berserk. But I might be wrong. Latex Boy definitely does, but his punch is not as quick.
So yes, Scot Bun is the strongest.
I will main him unless you nerf him somehow or buff the others.
Btw, for the Baron Fight, the FurDoom one is MUCH more dangerous than the HDoom one. They should be a bit more balanced? What do you think?
Ask me if you want my opinion on anything else!
