Hey! This is a great one-pager and I dig the looseness and freedom you give to the players and GM alike. Keeping that ethos in mind, I have a few suggestions for polish:
- I would try to reduce extraneous explanations to the bare minimum so you can save as much space as possible for rule explanations. For example, I think the first two sentences of the Roles description can be simplified as "Each role comes with special knowledge and some gear."
- I think the specific rule explanations are great (e.g. rolling and health) but it's a little vague in places, such as "negates electric damage" or "negates all chemical damage" - as a GM I'd be likely to ignore these if it's not referenced at all elsewhere, such as in the Consequence Ideas
- Generally speaking, I think these rules would benefit from an additional one-pager that gives Scenario ideas. Better yet if they provide character some character archetypes that players can base their own characters on!
I look forward to seeing more of this, especially some scenarios!
