Sparkseal

How it plays

Swipe or click to grow horizontal and vertical walls. A spark hitting a growing wall costs one of three lives; complete the wall and the empty side seals. Reach each area target to advance through 12 original stages, with faster darts, larger embers, split arenas and rising targets.

Why I made it

I wanted a clean browser take on JezzBall-style risk and reward: waiting is safer until it is not, and every successful cut changes the next decision. Touch, mouse and keyboard controls are supported, and stage unlocks, medals and best scores save locally.
