NOTICE: Chrome doesn't get along with this game. If you're getting lag, try using Firefox. The downloadable version should also work without lag or loading times.

The hero has a princess to save and a quest set before him, but there are unsettling signs that all this has happened before. As you play the game, you'll come to realize that the dungeons and monsters are meaningless distractions from the task of uncovering the truth.

Ouroboros was a quick experimental RPG I made last year based around a specific plot twist/mechanic. It has text-only sex scenes, but you won't find them until you're a ways into the game. I went back and did a remake later, which has art for the sex scenes and can be found at various sites.

This is the HTML5 port of the original. You should be able to play start to finish, but a few features had to be removed for it to work on Newgrounds (like enemy HP bars). The original is still free to download here:

Though this version is a complete game, an expanded version (with art for the sex scenes) can be purchased from here if you want:

I also have some completely free games that you can find here:

Those links are mostly SFW, but the games are very much NSFW. Anyway, hope you enjoy this little experiment!


Love the game but the fire amulet does not transfer between cycles

well this game is fun i just played my first playthrough because its amazing but my game crashed and some stuff took a long time to happen like special effects but i just had a problem i was in the ice dungeon and dayum entered a battle and it says: ''img/battlebacks1/IceCave.png'' and i forgot to save .-.
so if you guys excuse me i have to do stuff from my last save

P.D.:this game is amazing keep up the good work

I wonder, how long did it take you from conception to complete the story of this game out of curiosity? (Not making the game). I thought it was amazing. The only eroge I've played is fate stay night, and I've loved rpgs since FFX and grandia II, so I thought this was a welcoming blast from the past. It was very clever and well-written. I actually bought the 2.0 version for my first play through and marathoned it in one sitting. I feel some people might be put off by the hentai, but I can tell you're like an aspiring eroge game maker or you just like that kinky shit.... like holy moly that's an understatement. My favorite sex scene was the futa one with the shopkeeper... so darkly funny and hot in a weird way.

SierraLee responds:

It's hard to say the time from conception to complete story, because I had the original idea of a cyclical story in my head for a long time. When I started this project, I sat down and decided exactly which elements I wanted to emphasize and what kind of story would best support those. It was a few days before I had the idea mostly settled, though the idea evolved somewhat as I developed it.

I have ideas for all kinds of different games! If you look over my current games, you'll see a mix of kinkier concepts and softer eroge. Right now I'm focused on my ideas that work as adult games, but in the future I hope to expand further.

Glad you enjoyed the game! I knew I needed something fun for Amiel's route. ^-^

i need go by a trees!

Awesome game!
