If you’ve not been keeping up with Infinity Nikki, the dress-up RPG which already has over 30 million pre-registrations, then this overview trailer should help get you up to speed. It outlines the general storyline – returning character Nikki and her cat Momo have once again returned to the mystical realm of Miraland – as well as the overall gameplay loop.
The best way to think of this is a kind of blend of Genshin Impact, Style Savvy, and Super Mario Odyssey. Your main objective is to collect Whim Stars by using your different outfits to navigate the world. One dress enables you to jump, while another can help you to attack. As a live service game, you can almost certainly expect new costumes and gameplay to be added over time.
