Neat idea. It resembles Breathless SRD at first glance, but this tags and pushing rolls mechanic make it unique. Have you considered making character sheet?
I appreciate the comment, truly. I expect to develop a bigger version using the system over time - we're playing with it right now and seeing what we find ourselves in need of for sessions, to then add to the game properly. A little character sheet is definitely forthcoming. A basic Cairn style one probably pretty soon.
