The opponents (choosing paper) watch in horror, absolutely flabbergasted by my tactical mastery of the game, as I choose scissors for the 11th time in a row.
It's an interesting little game, but I dont feel it's worth the price. it feels like for this game it'd be a particularly fine line to walk, because, let's be honest, this is on par with a good flash game.

Horniness scale
Each game gets a score from 1 to 5 hearts. Higher means more explicit adult content.
| Score | What it means |
|---|---|
| 1 | Raunchy / softcore — suggestive themes, light fanservice, or mature humor; little or no on-screen explicit sexual content. |
| 2 | Spicy but restrained — clear adult intent (nudity, strong innuendo, or brief suggestive scenes) without sustained explicit focus. |
| 3 | Clearly adult — recurring sexual content or nudity as a meaningful part of the experience, but not the sole focus of the game. |
| 4 | Strongly explicit — graphic sexual themes, extended explicit stills or text, or gameplay built heavily around adult situations. |
| 5 | Explicit and often animated — graphic sexual content that is frequently animated or interactive; core to what you see and do in the game. |

Love the visuals and the side missions. The character banter is top tier.
Nyra
Story is solid and the combat feels great, just wish there was more UI customization.
Kiro
I keep coming back after every update. The new scenes were worth it.
