At the Island of Madness; The Hidder World

Hi and welcome to TWHL. Did you mean "hidden"? If not, what does hidder mean in this context?

yea Hidden

I like that you are making a big forest map, that's not too common. And you use sounds a lot, that's very important

You can delete most of the files from the download. Many are included in Half-Life already, and many others are not used by your maps. Your maps only use the following files:

Alien word.wad
chateau.wad
Cosmic Horror1.wad
CrazyD.wad
cs_cbble.wad
cs_havana.wad

If you remove the other files that aren't needed, you cut the size down from 580 MiB to 126 MiB. This means faster downloads and less space wasted. Of course, since this is just a prototype it's not a big deal

it's ok
