I've made a simple HTML5 game with Phaser during the Global Game Jam 2016 happening last weekend.
Theme was Ritual, so we decided to do a duel between a Shaman and a Witch. You control both - have to collect the potions as Shaman and disturb the Witch so she miss all of them. You can tap on the left/right side of the screen or use left/right keyboard keys.
There's a short blog post about the process of building the game.
