Alright, this might be long, but it will be helpful. Keep in mind, I'm a boardgame designer, not a TTRPG designer, so that will color my perspective considerably.
1.The second page can be removed entirely. It's not helpful to the game itself. Replace it with a description of the game-play. Specifically, what type of game this is. 'Is this a role-playing game? An improvisation game? A negotiation game? A 'take-that' luck driven game? A tactical combat game? A bluffing driven fighter game?
2.Flow of play is good. Solid. Simple. It has a few steps which need better explanation.
3.What is a 'Safety Tool?' and why is establishing that important enough to be step one?
4.This book assumes that someone has played a similar game to this in several places. Never a good assumption.
5.Give us an example of play between two players. The final page can be taken up with an example of play.
6.Reformat the 4th and 5th pages with bullet points alongside each set of instructions or such that each paragraph is a paragraph. It's presently very difficult to read.
7.Is there a ref? Do all the players describe their playing environment? Does just one player lay the scene for the fight and then everyone else fights there? Do you all agree on a location?
I like your concept here, but it needs some simple editing. It's a GOOD IDEA and seems mechanically sound, but formatting will help your vision come through.
