Ok, I've played through all the maps, and they were pretty great I must say. I like personally the simpler D1 style maps. But the fortress stage was pretty amazing, except listening to Cyndi Lauper for ~3h was pretty

.
There was one stinker though and that was the Patrick intestines one. You could not see anything and I found no health or armor. So I figured the best way to beat it was just to rush through the darkness and ignore everything until you found the end. I also didn't like that you had no map in Kaotic Fears. Running around in the maze(with portals) in darkness was not that great with no map.
Dialation Station 41 is too hard for the first map. I would put the tiny island map first.
Bugs.
YWNB has a door in the graveyard that requires a yellow keycard, but there is none in the map. I had to cheat to get around that so that has to be fixed. You can't beat it right now unless I missed something.
The performance in Kaotic Fears in the center torch/mirror room is pretty bad. Add to that that the stage loops through portals does not help. Every time I looked at that room the FPS tanked hard so I think that needs to be looked at. Maybe reduce the amount of times the mirrors reflect/hall of mirrors?
@Judge Dredd, you have put some graphics in the wrong folders so they don't work in game.
- TSCRN2.png should be in the "patches" folder. But it's included in the planet texture so this does not matter.
- COL6A0.png is in "textures" but should be in "sprites".
- PS20A0.lmp is in "textures" but should be in "patches". Right now all poison signs show the original graphic.
In the Balldo map the door sounds do not work. I could not find my custom sound sequence lump so I guess you never extracted it from the wad. I "think" it should be placed in the root and MAPINFO will find it.
Tweaks.
It looks like all the maps are designed for pistol start, so I suggest to add "ResetHealth" and "ResetInventory" to all maps in MAPINFO. That would also fix the problem of starting with too low health.
It also looks like no map requires jumping or crouching. I think you should add "NoJump" and "NoCrouch" to all maps in MAPINFO. I was able to get to spots you absolutely were not meant to be and/or getting stuck.
Only 2 of the maps does not allow for free look. Rats Den and Server Suicided I think. I don't think having free look in those maps breaks anything so maybe add it to those too so everything is consistent?
I think that's all for now. Good shit everyone!
Edit: Oh yea forgot, there should absolutely be a credits and "Thank You for playing" text at the end of the episodes.
