First of all, thank you for developing this mod.

While trying to grow White Puffballs, I found that they do not grow at all.
After reviewing the code, I confirmed that the growth and survival conditions in WhitePuffballBlock.java conflict with each other.

In the randomTick method:
level.getRawBrightness(pos.above(), 0) > 13
requires high light for growth, while the survival check requires low light.

I reversed the comparison operator and rebuilt the mod locally; growth then worked as expected.

Yeah I think the sign just got flipped
