Disappointing game. It has a lot of unique elements and does a lot of things right. Unfortunately, the emphasis on RNG and difficulty completely ruins this game for me.

The first few floors are quite enjoyable and have good difficulty scaling, but once you get to the latter half of the floors, it seems like you need to rely on getting a quick path towards the exit. On a lot of the floors I was able to get past, I spent most of my time staring at the health of my heroes just to make sure they didn't get melted by the swarm of enemies each time you opened a door. 

Maybe I had a few bad runs, but in my four hours of playtime, it was fun for the first hour, and after that, it was all downhill. The game also suffers from a really bad progression system; most rogue-likes get easier with each run, but with Dungeon of the Endless, you only unlock heroes, which in my experience doesn't make much of a difference. 

Dungeon of the Endless could've been great with a progression system that made it easier with each run and easier difficulty settings. I might revisit this in the future, but for now, I don't have any intention of trying to finish it.
