A.

and

B. https://forum.zdoom.org/viewtopic.php?f=43&t=56762

Any suggestions? For the moment I've found two exist in case of "straight forward" gameplay similar to Heretic, but can't find more...

2.

Shades of Darkness!

It seems it has some unique items / monsters.

Try Tower of Chaos and A New World. Doesn't have much puzzles overall, despite having a couple of hubs per wad.

Currently playing one. I guess I'll update list later with links to those.
