They system is VERY simple and meant to feel entirely free form to the players.
The system will have 4 statistics, each one meant to represent a different way your character can(or can't) deal with danger within the maze. These stats are as follows:
Strength: How strong your character is, which represents if they can manage to overpower a monster or device they run into. It is displayed as a number between 1-10
Agility: How fast your character is, which represents if they can outrun a monster that's chasing them. It is displayed as a number between 1-10
Perception: How easily your character can notice things which represents if they can notice a trap before stepping into it. It is displayed as a number between 1-10
Willpower: How much mental stress your character can take before going mad. For the sake of the game this stat will act as a 'health' stat. It is displayed as a number between 10-100(It takes the stat value you assign and multiplies it by 10)
Each character is given 22 points to distribute between their stats as they see fit. With the minimum for each stat being 1 and the maximum being 10.
The formulas behind the game are very simple and involve you simply making a post stating your intention of what to do when you encounter something. Such as "My character sees the monster and turns to run from it" or "My character stands their ground intending to fight the monster." (Hopefully in a bit better detail than the examples though
)This will be followed by a quick D6 roll (made by the GM) to determine if the attempt is successful or not. The result will then be played out in a free form manner. Each time your character falls victim to a trap or creature they lose a bit of their willpower(how much depends on what they fall victim to) and once their will power runs out they go insane.
