Hi! Some of my games are short projects for game jams, so they are free on itchio: two of them are also available on Steam, but to be honest, it's not worth it because it's nearly impossible to recover the Steam tax.
That being said, My Burning Heart IS available on Steam. Unless you live in Germany, China, or other countries where games with NSFW content are banned, it should appear on my dev page there. BUT you need to have the access to adult content activated on your profile, and be logged in. In fact, if you buy the game through itchio you can claim a Steam key along with your purchase (which is the best way to support indie creators like myself, and to bypass Steam censorship XDD).
