Creator-listed input

Build the team before game day

The creator describes ten trainable team skills, along with gathering materials and crafting bats, gloves, balls and uniforms. The game follows a named ten-player roster from a neighborhood field toward a league championship.

Follow a season and keep progress

The page describes pitch-by-pitch simulation, an 18-game season, playoffs, standings and field upgrades. It says progress continues while away and offers a browser save code; Joywisp has not tested persistence or the simulation.

How to choose

The creator page describes an idle game but does not specify keyboard, pointer or touch controls. Choose Diamond Idle for team planning, crafting and a defined season objective. Talewyn Harbor instead centers on fishing and open-ended exploration; the creator pages do not supply comparable session lengths.
