Nameless is an otome game created by Cheritz. Their first game was Dandelion Wishes Brought to You. I highly recommend playing Dandelion and then Nameless. Though it’s not really necessary, it’s nice to see the relation between the two. Moreover, all the Dandelion references in Nameless were a delight to see! I made a post about them here (though I’d recommend to take a look only after you finish playing both games since it contains spoilers).
You can check out the official site and Nameless can be purchased here. It is quick and easy to make an account and purchase the game. It is priced at $30 if you’ve previously bought Dandelion and $33 if you haven’t. In my opinion, I found this to be well worth the price. Nameless completely blew me away. I already had high expectations due to Dandelion, and I certainly was not disappointed.
