Application Description

Experience a dramatic high school baseball simulation! Cultivate uniquely talented players!

# Game Outline

My lifelong passion for baseball games inspired this high school baseball simulation, built around the most exciting concepts I know.

The goal is to develop players as distinctive and compelling as the protagonists in baseball manga.

The game offers a well-balanced experience, whether you focus on hitting, defense, or power development.

We’ve paired dramatic moments, like a game-winning hit, with epic background music and signature callouts to heighten the excitement.

This title brings all those elements to life.

Take on the role of a high school baseball team manager. Nurture players with unique traits—like a pitcher with a wild fastball but poor control—and guide them to victory in the prefectural tournament and the national Koshien championship.

This is a "dramatic high school baseball simulation" designed for players who enjoy pure strategy and development, with no gacha mechanics.

# How to play

Direct player development by managing their practice regimens.

Fielders train in contact, power, speed, defense, and intelligence, while pitchers work on their fastball, breaking balls, control, and stamina.

Create a personalized development plan that fits each player's unique personality.

Our players are full of character, leading to intense development stories like these:

A gifted pitcher overcomes the yips to find his true potential!

A complete beginner (all G-rank stats) focuses solely on hitting and earns a starting spot by his junior year summer!

Furthermore, game balance has been refined using extensive player feedback from our development period, ensuring there's no single "must-win" strategy.

(We've incorporated tons of feedback from dedicated players to eliminate any overpowered tactics.)

So, discover your own approach to development and build a team of standout personalities.

Training progresses month by month, with Koshien qualifiers in July and September. Win your qualifier to advance to the national tournament.

Before each game, set your starting lineup and batting order.

During games, you'll make tactical decisions as the coach.

You can call for bunts, stolen bases, squeeze plays, hit-and-runs, or aggressive leads.

Tactical instructions consider nuanced baseball situations, like how a grounder might play differently with runners on first or second.

To visualize this, we include animations for batted ball outcomes and defensive plays.

In critical moments, your teammates' passionate cheers fill the screen, and dynamic cut-ins with decisive lines amplify the game's intensity.

Staying true to high school baseball, seniors retire after the summer tournament.

We are planning a "User Koshien" feature (not in the current version) where users' teams, saved just before their third-years retire, can compete in tournaments.

We also plan to host official User Koshien tournaments.

# Report a request or problem

You can report a request or issue anytime by clicking the "Report" button on the left edge of the screen.

As a solo developer, my responses may sometimes be delayed, but every piece of feedback and every bug report is valuable and directly informs the game's development.

This game was previously released on Windows and has been continually improved over the years based on user requests (we've addressed over 100 to date).

# Windows version

A Windows version of this game is also available.
