Superbubble

Superbubble is a fast arcade catcher set inside a glowing nebula. Drag the
bubble film along the bottom of the screen with one finger and catch the
stellar wind motes and golden heavy elements raining down from the star
fields above. Every catch adds mass, earns star coins and makes your film
grow wider.

But the wind carries danger. Red supernova shards puncture the film and
shrink it, and a bubble that gets too small bursts and costs a life. Missing
good particles drains your lives too, so stay sharp.

Fill the mass gauge to clear a sector, then dive deeper where the wind blows
faster and the shards fall thicker. Spend star coins in the shop on six
permanent upgrades: Bubble Plating, Gravity Magnet, Time Dilator, Spare
Membrane, Dense Core and Plasma Coating.
