Kelph Venth controls a floating sac with opposing short swipes. Swipe upward in the upper zone to inflate it; swipe downward in the lower zone to vent. Reversed movements waste your gesture.
Enter the narrow band from outside to earn a ring and start a stackable combo chain. Clear wall heat to gain a side bonus. Touch a burst or collapse zone, and your run ends instantly with no remaining lives. Staying outside the band only breaks your chain, keeping your total score intact.
The band drifts automatically. As you progress, it narrows and moves faster, with heat building up sooner.
The lobby features rules, a preview, then the start button. Your score appears in a left-side panel, combo text sits beside the sac, and the top and bottom areas remain uncluttered.
Swipe up to inflate, down to vent; park the sac inside the drifting band.
