I have decided for the time being that when I do the character class/abilities I will follow Aaran "Relentless96" White's advice and use the same progression as I used for my tables: d4,d6,d8,d10,d12.
My main decisions on this next is target numbers. I am of two minds.Either I could say that the d12 is the strongest and roll high.That could make combat resolution easy.Subtract low from high and the difference is damage comes to mind.That would make lvl V d12 characters powerful.The other way is to make the d4 the strongest and roll low.As you make your way from d12 down, you remove chances for your failure and increase your odds of success.
Here also is a brief exploration of "content dice" also suggested to me by Aaran. If I explore this direction too much further,I will definitely not be able to keep the game to a page, but then I might keep my one page game idea and use it for the core of a related game using these kinds of extra tables.
The Dungeon Table
-Start by rolling 1d4
1 Entrance/Way Out (rest,move on,move up or down 1 level)
2 Passage Way (rest,move on, find the Way Out)

This is all looking very good
Your game seems to be proceeding nicely. If I may, here are a few things to keep in mind when making a one page RPG:
Do you want your one pager to be one-sided or two-sided? A one-sided one page RPG has one page in pdf form that is printed out on a piece of paper where you leave one side blank. A two-sided one page RPG has two pages in pdf form that are printed out with one pdf page on one side of the piece of paper, and the other pdf page printed out on the other side of the same piece of paper. Hence, the one page RPG.
Is your one pager going to be a character sheet RPG as well? A character sheet rpg is a roleplaying game that functions as it's own character sheet. As such, a character sheet RPG needs a section or sections wherein the player writes down all the pertinent info. If your one pager is not going to be a character sheet as well, then it does not need such sections.
Besides the main design of the game rules, you'll also have to factor in the design of the pdf file that will be the game. You can even include artwork if you have the space. Here is a link to my blog which names all the one page submissions for the 2007 challenge. If you like, you can check out the submissions for all the various ways to design a pdf for a one page RPG. Good luck!
Peace, Errin : )
