Green Push has no XP skill.
Squares focused on the blue level. More squares focused on the red level. I knew that from the get go and still wondered how far it could go.
I spent an incommensurable amount of time on crystals - T5 base, 1.4bn mana, 738x collection, 147x speed - so it will still take me 7h to fill the first row. With green skills I may have pushed further but it does feel like I'll have to wait for Morer squares instead.
