Hello again Ponydragon, thanks for your feedback. I'm not sure what do you mean by the reroll part -- the mechanical effect is to make the success margin greater, the narrative outcomes in TTRPGS are generally decided by the players. There is some help of the narrative implications in the middle of the manual, but that's admittedly very short due to my self imposed limit of pages. To quote a specific part:
"Lucky you for having the power to return
from dead, remember that it takes you to the last test you failed (the one leading to your assassination). You can choose to repeat that action taking advantage of your new acquired knowledge or start a new chain of events."
it's not my intend to give players a story as in a module, but a ruleset and guideline to build a narrative -- as traditional in manuals of tabletop rpgs played solo.
Thanks again for your time, even if you didn't play the game -- reading the guide is already much appreciated. I'll try to apply your advices best I can.
