Well, the base concept is pretty niche and I'm limited in what I can do to make it easier to tackle with.
There is an option to facilitate the timing required to get chromatic creature if you want ("Encounter Assist" in the "General" option menu).
It corrects your timing automatically if you are off by a small margin. You can crank it up to 8 if you want, which is about a second of leeway (-0.5 to 0.5 seconds around the correct timing).
But yeah, kinda hard to find a way to introduce all the concepts without getting boring. I have a plan for that in the future, but for now it's just a big game manual to read...
