This is a super fun hold. If you haven't played it yet you should definitely correct that mistake immediately.
The Trapdoor War level alone is enough to warrant an 8 or 9 fun rating. Apparently loosely inspired by the game Patchmania, this level manages to take four simple elements and make some mind-blowing minimalist puzzles that, no joke, give Jutt a run for his money in terms of pure elegance. I... I had to use graph paper to solve some of these rooms. It was beautiful.
Other levels are solid fun too. There's a lot of variety for sure. Sphere Frontier has a nifty scripted element, also based on another game. The two other levels focus on tricky linchpin puzzles with a dash of monster manipulation. Some of the linchpins are quite tricky; Trooper Stupor had some crazy rooms with alternate weapon guards that left me totally baffled at first. Expect to see some rooms that really test your understanding of DROD mechanics.
All in all, this is a great hold. I'm only about halfway finished with it, but am loving every moment. This is definitely one to check out.
