* The "Energy shuriken" shop upgrade gives you 3 Ki charges. With additional shop upgrades, it can be increased to a total of 5 Ki charges.
* If you don't own the "Energy shuriken" shop upgrade, then collect all 45 Power Seals, and then open the Power Seal treasure chest in the shop to unlock the Windmill Shuriken, you'll automatically unlock the "Energy shuriken" shop upgrade without having to pay for it.
* You need to own the Wingsuit in order to obtain the "Aerobatics warrior" shop upgrade.
* You need to die once and meet Quarble in order to obtain the "Devil's due" shop upgrade. After purchasing "Devil's due," Quarble sticks around for 30 seconds instead of 60 seconds, assuming no Time Shards have been collected.
