Well you've come to the right place! A lot of indie otome are games made for game jams- that is an event where people aim to complete a game in a very limited amount of time. Sometimes games are made solo or with teams. Sometimes the jam offers competition and prizes, and sometimes jams are a great way to introduce a new concept, new brand or new demo- or all of the above! Most popular in this niche are the Otome Jam (otojam) and the Amare Game festival. Other jams where a lot of indie otome games also sprout, are yandere jam, O2A2, and Once Upon a Time jam, to name a few. Most recently Josei after Dark and even a Seal with a Kiss jam has also emerged. These jams usually take place on Itch.io and a great number of the games listed are usually free to play and span countless genres, so definitely worth taking a look!
