Thanks for your feedback, and I see what you mean by nothing being "taken". Although I do feel like I need to make one last defense for theme, more or less as food for thought I suppose.
If I had re-skinned the game to be, I don't know, an (A)ssassin, (S)orcerer, and (D)ruid running through a dungeon, made the enemies into monsters charging down the corridors, and put up a little message when you spawned a new character saying "It's dangerous... take this". In retrospect I probably should have done that, but if I had would you still question the theme?
If your answer is yes, by all means rate theme how you see fit, just wanted to get that out there. Oh, and thanks again for the compliments! Looking forward to trying out your games. I should stop commenting on my own game now...
