Unicorn Slime

Unicorn Slime is an Arcade game you can be inside of about a second after clicking. Taps and swipes are the whole vocabulary — a phone plays it best. Listed under arcade, color, html5, hypercasual, kid.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Close the tab and come back later; the game is still one click away.
