Thank you for posting this! I've played Heretic really lot in my life, as it was my first 3D game I owned, even before I got Doom. Nowadays I am playing various level packs and "megawads" for Heretic. There are not so many of them as there are for Doom, so I'm always looking for some new Heretic stuff to play. And you definitely came in handy to me!
I'm sorry for so much late reply. I actually read it once you posted, but I had quite few time to play something. But right now I finished the last level of your Wad and I'm going to give you a some feedback/review on this.
Power Trip is definitely an arcade-style level pack. It does not focus on realistic and detailed level design, as I was used to when I played some other mappacks. So the visual style is not the best, and the locations look very abstract. On the other hand, it was really pretty fun to play and I loved some of your interesting ideas and even some "fun" and "surprise" elements, like some crazy switches, switch puzzles, the level names and so on. I liked some particular sections, like killing monsters with these respawning exploding green balls, the beginning of the ice level where I could kill so many mummies with time bombs (so satisfactory, oh yeah) and so on. It was not very hard and the levels were pretty short, so playing it was relaxation for me (compared to some extremely hard and challenging Doom megawads I'm playing). After finishing some levels I actually realized that each level was designed to be played from wand-start (I mean playing without weapons, ammo and items preserved from the previous level). If I started each level like this, it would be definitely much more fun and challenge to play. And the last level could be finished without firing a single shot, but just running around and let the monsters infight.
So that's about it. Thank you for providing me something interesting to play and hope you appreciate my feedback.
PS: I really admire how much effort you put into making the trailer video. I suppose it took you even more work than to make the levels themselves, hehe (jk).
PS2: I've also made one level for Heretic myself. I think it's pretty good so I strongly recommend you to try it out. Get it here:
