An android game available to play for free on Google Play.
-IS- is an endless vertical-scroller, similar to Flappy Bird, where the player controls a ball instead of a bird. Unlike Flappy Bird, where you tap on the screen to guide the bird through metallics pipes, -IS- requires you to drag the ball around to avoid obstacles placed on both sides of the screen. Additionally, -IS- features a gacha system where one can spend in-game currency, acquired by collecting light particles randomly appearing on the screen, to unlock a variety of balls in different colors and shapes.
