Hello, what's exactly tour beta ??(Sorry, I'm not a native english sepaker)
If game will be offically relased, tour beta edition will still be worthful??
Beta means you get to play first before the game officially releases. Right now, only Toru (the red-haired guy) route is playable. When the other guys' routes are finished, the beta will be updated (so you will be able to play the other guys' routes as well).
When game official releases, you also get to download the "full version" as well.
