It's every RPG ever
I actually love this game from a conceptual standpoint; frankly, it's a caricature of every RPG. This is exactly what any RPG would be if all the story were ripped out. Essentially it boils down to the mindless grinding cycle, i.e. killing monsters so you can get money and level up to progress more floors and fight more monsters and so on. When you inevitably lose, you want to do it again to see if you can do any better the second, or even third time around.
If you designed your game specifically to critique RPG's, then I would have gladly rated this much higher. However, it seems incredibly doubtful that it was intentional, which makes it an incredibly bland and boring game.
