I could hear the opening sound of the title song vividly as soon as I read that. I liked it but somehow never played it much. I think it was missing a little bit here or there.
Just because it has random level generation/is a roguelike does not mean it has endless replayability. Generally, if you have seen most random events and it's not really challenging anymore because you got "too" good at the game, it loses its appeal for many, as it did for me.
What I'm asking was more in the sense of, have I missed things? Is there more content than I thought there was? I thought for a roguelike it had pretty limited alternative options to see. Essentially, what makes your 100th run different from your 99th run?, and the answer for me was "not much"
