Little Black Box

Little Black Box is listed here under Hypercasual. There is no launcher and no install between you and it. Designed around touch input, and comfortable on a small screen. Catalogued as arcade, html, hypercasual, jump, jumping.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. It costs nothing and asks for nothing: no registration, no download, no launcher.
