Upgrading the upgrade to PoF
“Look like the innocent flower, but be the Obaba under’t.”
You can purchase an upgrade to the premium version ingame with gems (2300 IIRC). You cannot purchase the ultimate upgrade with gems, it wouldn’t make sense because you would pay 4000 gems to get 4000 gems.

If you want to upgrade to the ultimate, you have to request a refund, then buy it instead. If you want the deluxe, it’s in the gem store.
