Astro Pong pro

Astro Pong pro is a Hypercasual game you can be inside of about a second after clicking. Designed around touch input, and comfortable on a small screen. Its tags here are .io games, arcade, hypercasual, spaceship.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Free to play in the browser, with no install step between you and the first round.
