Finally I get around to reading this review! Life's been keeping me busy. Glad that you enjoyed the game.
The One-Shot Wizards were a personal challenge: I've heard folks say that you can't ever put Wizzrobes in a dungeon till level 6 or later. To do so is like some big design faux-pax and means you are terrible and your game is terrible. And I said to myself "CAN SO." So that's what I tried to do. On the other hand, I just really like Wizzrobes. Starting to think its unhealthy.
If I ever get around to making a sequel to this game, I'll do a better job with the difficulty curve and more intuitive design.
(But there will still be wizzrobes. :3)
