Lianhai Billiards Club gets an alpha demo you can download over at its Steam store page, an anime visual novel and pool / billiards game, developed by 致意. The game also goes by 连海台球俱乐部 or ウィナーズブレイク.
The game can be divided into two parts, “Role-Play” and “Billiards”.
In Role-Play part, players can explore freely in the school and in the city of Lianhai, looking for plots that can be triggered and developing relationships with their partners.
As your bonding with your partners deepens, you can acquire special skills for use in billiard games. (e.g. sight line visualization, etc.)
Every once in a while, there will be an important billiard match event where players need to use their honed out abilities to win the match and advance the plot.
