I'll try not to post when I'm tired as fuck so this doesn't happen again.
[edit]Also, I played a little through this.
I got to the start of map 2. The weapons feel a bit weak...
And now a non-raging version of my previous post:
[/edit]Please remove those files from the WAD and put them in the PK3 itself
No. Seriously. It has to load the entire WAD to RAM to be able to use it. 94.75 MB of RAM wasted for nothing.
Also, convert all those audio files to OGG and remove all those duplicate audio files/audio files with the same exact name.
