Deadly Rooms of Death is a great indie dungeon crawler/puzzler which, unfortunately, doesn't receive the attention it really deserves. The latest entry, The City Beneath, expanded upon the already magnificent puzzle-based gameplay in a myriad of ways. It was also released last year (in April) to little fanfare except in the indie community. Thankfully, though, there is now an official trailer that shows off some of the excellent gameplay elements. You can check out the embedded video after the break. If it interests you, check out the main site for a demo and ways to get the full version.
