My Summer Love: Memories

My Summer Love: Memories is a romantic visual novel that captures the aesthetics and nostalgia of 90s Full-Motion Video (FMV) games. But this is much more than a traditional dating simulator: here, you have total control over what you say.

The End of Predefined Dialogue Trees

Every single interaction is unique, reacting in real-time to your personality, your questions, and your answers, creating an immersive experience that changes with every playthrough.

Absolute Privacy: 100% Local AI

Your privacy comes first. All language processing in My Summer Love: Memories runs completely locally on your computer.

• No internet required: The game does not require a connection to external servers or third-party services.

• Anonymous and private: Your conversations with Yuna stay on your hardware, guaranteeing a safe, secure, and private experience.

Independent Engineering: Our Own Custom Engine

To create a game with these characteristics, the available game engines (such as Unreal, Ren'Py, or Unity) are not suitable. We needed absolute control over memory and multithreaded parallel processing capabilities to load videos in real time while dynamically generating text. Therefore, at Soul Shell, we developed our own engine, the RetroSense Engine, from scratch using C++ and the following open-source libraries:

• SFML for multimedia management.

• llama.cpp for the efficient execution of local Large Language Models (LLMs).

• Dear ImGui for a clean and optimized development interface.
