I recently finished my first game with Phaser in just under 2 months. Its a 2D action / bullet-hell style shooter with a story, made using Phaser. You can play it here: SUPER STARKILLER 3000
I also wrote about what I learned in a retrospective you can read here: https://github.com/fahseltc/SUPER-STARKILLER-3000/blob/master/docs/article/postmortem.md
