Growth is HARD. It is much harder than the previous two levels. Even though I have the entire level memorized and know how to do every section, around 90% of this level is "difficult" and there is much less tolerance for error. On the up side, much of the difficulty is concentrated earlier in the level, so restarting repeatedly to achieve a high streak doesn't take up as much time as, for instance, Transition, which has only one notably difficult section that appears about 10 minutes in.
