About this game
A “non-frustrating” 3D action game where you jump upward
Chase your heart into the sky. In an anime-inspired world set in Japan, a charming office lady challenges boundless heights. Jump, climb, and sometimes fall—all to catch the “heart balloon” a boy let go. Checkpoints are placed throughout, allowing instant recovery with a single button press. Auto-save is also supported, allowing you to progress bit by bit even during short play sessions. Advance through the game to unlock new outfits and freely customize your appearance. Mystical stages inspired by Japanese cityscapes, shrines, and aerial gardens hide multiple paths leading to the goal. No matter how long it takes, if you don't give up, you will surely reach it—a story of climbing “upward” slowly and steadily, alone.
Features
This is an “Only Up!” type game. However, a single mistake won't be fatal; you can resume from checkpoints at various locations. If you keep progressing, even little by little, you will definitely clear it. We've minimized the “unfairness” and “endless backtracking” common in this genre,
focusing instead on the world's atmosphere and the pure joy of climbing anywhere.
It's also designed for casual play in short bursts, perfect for those who can't dedicate long stretches of time.
Touch the pink backpacks scattered throughout the stage
to change into different outfits.
You can also change into any acquired outfit at any time from the settings screen.
Not just climbing upward, but there are also stages and effects that let you enjoy the worldview at various points.
