Bubblebound

Iris and Arke are two siblings, of which Arke is an excellent scientific researcher. One day when showing off a new invention, Arke's invention blows up and sends both of them flying into different worlds. Desperate to find Arke, Iris uses the scattered pieces of Arke's lab from the explosion, a magic bubble wand and other collectible relics to upgrade her ease of world-hopping to find Arke. Inhabitants of both worlds are hostile to the two anomalies, gravities are confused, and Iris must navigate them all to get to the one who can solve this calamity before it's too late.
