Silence - rough base mechanics

Okay working on the basic mechanics for Silence (my Silent Hill inspired rpg I want to run).  I really want to keep it very simple, as little note keeping, detail tracking, etc as possible.  So I wrote down a sort of outline of how I want the rules to work.  This is a completely rough draft with no actual meat put into it whatsoever.  Just me dropping down idea onto the blank page. 

Here is the thoughts on traits, combat and a bit about challenges.

----------------------------------------------------

Four base traits. MOVE, FIGHT, THINK and HIDE.  Rated from zero to three.

Use just ten siders with the goal of rolling high.

At a zero roll two dice and keep the lowest

At a one roll one die

At a two roll two and keep the highest

At a three roll three and keep the highest

Goal is to roll higher than the difficulty of the action.

In hand to hand you roll FIGHT vs FIGHT. The amount you roll over your opponents roll is the amount of damage you do. Weapons will add a set amount more.

There is no initiative roll. If the GM thinks you surprised them then you roll vs a target number for damage or give you a extra die in your FIGHT roll.

HIDE will almost always be vs THINK

MOVE vs MOVE when trying to outrun something. Can also be used vs target numbers to make jumps, get out of the way of something quickly, etc.

THINK will commonly be used vs target numbers.
