Prerelease patch 0.13

Another pre-release patch! This pre-release patch focuses on groundwork improvements and performance optimizations that will support future features and provide a smoother gameplay experience overall.

Kana statistics tracking

We’ve added backend support for detailed, per-kana statistics tracking. This allows us to record how often each kana is shown, how many times it’s guessed incorrectly, and how often it’s answered correctly.

Although these statistics aren’t shown in the UI yet, collecting the data now means that once the frontend is implemented, your historical progress will already be there :)

Initial texture caching

To reduce possible stuttering during gameplay, we’ve improved how textures are loaded at startup.

Previously, the game preloaded around 60–80 textures during the loading screen, with the rest streamed in as needed during play. We’ve now expanded this to preload roughly 100 key textures up front.

The engine tries to preload textures it guesses you’ll encounter next. This remains a careful balancing act between memory usage and performance, but when tuned correctly it significantly reduces stutter during gameplay.

We’ve also removed several unnecessary resource loads, further improving startup efficiency and keeping memory usage in check.

Save system improvements

The save system has been optimized to completely avoid unnecessary writes to disk.

Previously, the game could trigger saves even when no new data had changed. We now only write to the save file when there’s actually something new to store.

This reduces disk access, improves performance, and is friendlier to the system overall ❤️
