Welcome to the forums Antero! I just played through your dungeon, here is a little review.
Gameplay: 5
There is nothing much to do. Long corridors, open rooms, lots of monsters, no puzzles.
What I liked was the restricted runes, especially that the power runes were not all available from the start. Too bad that the YA rune was located so far down, as having to sleep in order to regain stamina was a bit annoying.
Originality: 4
Nothing too special to see here, it's just another dungeon after all.
Difficulty: 3
Very easy. You usually have plenty of space to dodge the monsters which aren't that hard in the first place. Apart from one certain room with skeletons, there are no hard places.
Puzzles: N/A
Sadly, there are no puzzles at all to be found in this dungeon.
Size: 3
I played through this in 1 hour and 5 minutes, killing (almost) everything there is. It's really very small.
Replayability: None
No alternative routes, no secrets, no unlockables.
Craft: 6
It's a bit weird that most items in this dungeon are carried by monsters, and I wasn't too happy with the YA rune so far down. But everything works fine, and the skeleton room is quite nifty.
Game Ending: 5
It goes on longer than expected, and the fights get a bit harder in the second half. The ending itself isn't anything special, though.
Atmosphere: 5
Hey, it's DM wallsets with just a few tiny texts. Nothing too special.
Overall: 5
There are lots of monsters to fight, but it's not very interesting since everything is so easy and straight-forward. The dungeon desperately needs puzzles or more traps like the skeleton room.
Best part:
The skeleton room (you could probably tell this by the number of times I mentioned it

)
Worst part:
Not having any puzzles.
