In Train Modification Osawaru, players are introduced to a seemingly innocent and reserved schoolgirl who inadvertently enters the protagonist’s environment—setting off a transformation that drives the game’s narrative forward.

While the game offers solid visual elements and smooth animation quality, its core gameplay mechanics are relatively simple. Progression is driven by pressing the correct inputs to enhance your character’s abilities, eventually unlocking full control over in-game scenarios.

The initial pacing of progression feels balanced and engaging; however, the acceleration in difficulty and unlock speed can quickly become overwhelming, diminishing player immersion. Additionally, the game’s short runtime leaves little room for meaningful development, and the rapid progression can make certain interactions feel rushed or unsatisfying.

Though visually appealing and easy to pick up, the game struggles to maintain depth and consistency throughout its brief experience.
