I've read the chapters you recommended, and I can indeed use a new Spark this way, but... I can't help but wonder: does using all these Sparks really make the game as easy and beginner-friendly as it claims to be? I realize that with this question I'm going a bit off-topic, but in a classic game, combat is like 'you took 10 damage, you have 2 armor, so you lose 8 hit points.' Here, on the other hand, I would need to start a new Spark in addition to all the ones I already have for everything that's happened to me previously during the rest of the game, ending up with a table full of Sparks to keep track of all at once.
For now, I've only simulated a couple of isolated situations; I haven't played a full session yet. But so far, I have the feeling that relying on Sparks so often doesn't make the game as simple as it seems...
