Why popping bubbles feels so satisfying

There's a small, well-known burst of relief in popping a bubble — real bubble wrap included — and Popper is built entirely around that feeling.

Each of its 50 shapes is made purely of bubbles, so the satisfaction compounds: pop enough of them in a row and the whole picture clears at once.

Unlike a lot of 'satisfying' games, there's nothing hidden underneath and no ad break waiting at the end — the popping is the whole point.
