Thankfully, the Main Hub is available for unlock after completing the first ten stages, according to PCGamer. The game doesn’t exactly let you know that, however, and it’s tempting to hang back and try to grind your best times on the tutorial levels — but you’ll have plenty more time to come back to them, as well as access to more content after getting set up, so make sure to step back and unlock the hub as soon as you can.
It’s also worth noting that there are hidden Gifts in the platforming levels that you can give to NPCs for additional cutscenes and sidequests. As with unlocking the Main Hub, these are more than worth slowing down and looking for: Not only do they provide more insight into the central mystery of the plot and the play character’s connection to the rest of the cast, they offer their own challenges that’ll most likely have you using your cards to their full potential.
The bottom line? Experiment, have fun, but don’t be afraid to slow down and explore. “Neon White” is currently available on the Nintendo Switch, and PC through the Steam storefront.
