Really enjoyed the old school feel, and all the broken bricks and parts where you could see into other sections. Combat was ok, never too difficult and ammo was plenty.
Some strange parts I got stuck at, a portal that opened but I couldn't enter, and figuring out how to progress past the rocket launcher, but otherwise no big deal. Couldn't find the super secret...
Good job. E1M3 lives again!
