I feel I should mention that when going through TUCQ assets, at least in Release 5, I noticed TEKWALL4 and FLOOR5_4 are from the old stolen Chex Quest 3. They should probably be removed. There may be other relics from the old CQ3 that I assume you put in when you planned on porting those maps to TUCQ.
EDIT: Another idea I thought of, you should try adding in some brightmaps. It'd look good on textures like the lights in Caverns of Bazoik, and you could add them to the flemoids eyes, which would kinda add a fun cartoony factor to them, since whenever it'd get dark in a room you'd only be able to see their eyes walking around in the pitch black.
