Marble 1

thank god Underhalls was the map that followed this mod as that level was able to remind me what actually competent level design looks like.

Not that bad, even kind of interesting find the secrets in the map! But yeah, that switches jungle is a awful choice really.

A basic and nice looking showroom type of map where monsters are trapped inside glass prisons, no exit and no way to play this with any modern source Port like DSDA-Doom and GZDoom, but works really well in Crispy Doom. It was a pleasant experience.

Conceptually not bad, it's a pretty imposing tower with some decent lighting, but no ammo at all despite having the guns and a VERY obscure way to rise up the floor in the lava pit? That's a big downer. But overall, it's ok.

Well, the map is pretty basic. The map is quite challenging, with there being 0 ammo pickups (excluding the backpack) outside of the starting room. There are also nazis for some reason. I will give it 2 stars only because this really wasn't meant to be played to be enjoyed, but rather just a example of how to build a map in DEU.
