Dungeon raiders isn't like, awful per se, it definitely brought a lot of new interesting stuff to the deathrun table, but a lot of it was pretty hollow and would lose its charm after the fourth dungeon run. The map design was the only notable feature I can think of, but apart from that the game feels a lot like a hack and slash with no energy. Not the designer's fault that the melee combat in blockland is generally lackluster, but that limitation needs to be worked around
