Hi! Thanks so much for playing!
Strange, the character switching works just fine when I tested it. All the characters have their own slots on the D-pad. Did you press down to choose Dewy (the water guy) and right to choose Ember (fire guy)?
Yeah the xbox controller controls can be a bit... challenging when using Ember. The keyboard might be a bit easier if you want to give it another try :)
Thank you for your kind words though. They mean a lot.
