Unable to collect baubles from 250+ (bug?)
It’s not a bug, it’s a feature!
No, really, it is. Check the shops and look for an upgrade that will let you collect more baubles at a time. There’s at least one, maybe two. If all else fails, ask around or check the wiki/Dulfy for answers to where to find them.
Good luck!
delicate, brick-like subtlety.
It’s typical of the 8-bit game type that there are all sorts of arbitrary limits. Embrace the retro style (as a few of my friends do) or run from it (as I tend to do).
There’s one wallet upgrade each for sale in world 1 zone 3 (costs 250 baubles and upgrades to 2 stacks/500 baubles) and world 2 zone 3 (costs 500 baubles and upgrades to 3 stacks/750 baubles).
Getting those upgrades also counts towards the achievement of buying SAB equipment.
As mentioned by others, this is intentional and requires you to upgrade your wallet.
Side note and at own risk (in case prices change), continue coins are interchangable for baubbles at a rate of 1:10 (at Moto outside) meaning you can store a lot more baubbles (in continue coin form) per stack. Just make sure to take any required amount of baubbles with you if you intend to buy something from one of the stores.
