I played through a few times. The premise pulls you in right away and the creatures you encounter are engaging. The shadow's role is intriguing, and it is always nice to have a mysterious guide. I do wish there were a few more options on how to deal with them, having a small quest being offered instead of combat was a nice touch so would have liked to see more of it (like if you could side with the roaches instead). 

I liked the room with a mysterious drink that I of course drank, as any good dungeon explorer should.

There were a few logic breaks (if you meet the cockroaches first and then go to the 'killer of insects' room he is gone with no way to encounter him) but those can be ironed out pretty easily. 

I throughly enjoyed my time in the Most Dangerous Dungeon of All Time™

Nice one. I really liked the humor throughout. It bugged out quite easily, but I managed to find a workaround and get to the end. Great job!
