Neat hold, especially for your first one! Layout and aesthetics are top-notch. Puzzles were medium-ish difficulty and mostly pretty fun. The combat-heaviness really feels like classic DROD, while adding a few neat lynchpins to the mix.
I feel like checkpoint placement is suboptimal, and some rooms even miss them entirely. Since I'm so used to paying with UU now, I can't really say which rooms are really bad and which are ok.
Attached my set of demos. Room specific comments:
Entrance: Good room, and good intro to what the level is going to be like.
1N: I feel like there may be a few too many roach queens here? Made manipulating the wraithwing a bit of a pain. Maybe that's the point, though. It's definitely not too bad.
1W: Honestly, I'm not too fond of this room. It becomes clear very quickly what you have to do, and then it's just busywork. The roaches aren't really challenging to deal with, either, they're more annoying than anything.
2S1W: Way more fun than I expected it to be. One of the tougher rooms, I think.
1N1E: Toughest room for me, but also pretty enjoyable. For some reason, even after I figured out what to do, I felt like I had lost because the roach queen would escape when I hit the fuse. Probably I'm the only one to blame for this, though.
2N1E: Pretty standard old-school puzzle, but enjoyable enough. However, there's a backtracking issue here, since you can't return from this room.
1E: I feel like this room becomes a lot tougher (maybe even unsolvable) if you don't enter with your sword facing SW, but I'm willing to consider this a lynchpin here. Once that's down, the rest kind of falls into place.
1S: Pretty forgiving queen manipulation, which is always enjoyable. The end was a bit tough, but neat.
2S: Neat twist on the usual rotational constriction. The first order I tried pretty much worked, though I had to redo the third section.
1S1W: Another room I didn't care for too much. Was it intended that I could just use both eyes to hold down the pressure plates? After I figured that out, it mostly turned into busywork.
Anyway, off to a pretty strong start
