Good but glitchy
This was really fun, despite it being short, but I also found some problems with glitches. When you get the first "50 exp" packet thing, (the one in the dead end) and then go down the opposite hallway there is a spot where you can stand and get unlimited exp. I don't know who else got this but I know I did. So when I leveled up to about level 35 or so in about 5 minutes, I countinued playing. That's when I got the second glitch. I went from one room to another but instead of going to the next room, I stayed in the same room and I couldn't leave. So those were the technical problems I faced. As for playability, I felt it was rather bland and didn't have much variety, which I usually like. However, it was a good quick dungeon nonetheless.
A map would help! I got lost a lot. But maybe it's just my sense of direction...
