About Hexamental: Hexagonal Incremental
Build, rotate, and reshape Hexes to construct your ultimate Marble Run.
Guide your Marbles to unlock new shapes, and new ways to grow.
Expand your creation perimeter by perimeter - every completed ring scales your Marble Run - and unlocks deep new layers of progression.
Enter Skill Tree Mode: a living mandala built by your own hands, where rolling Marbles passively grow your skills while you idle.
Arrange your Hexes into perfect, symmetrical loops, generate Bubble EXP, and level up your abilities.
Bring those upgrades back to Marble Run Mode.
Build faster, reach further, and watch your careful layout transform into a sprawling, chaotic, self-building masterpiece.
