Eat dew. Grow your blade. One clean hit wins.
Eat glowing dew to grow from a tiny Seedling into a towering knight, each form with a longer blade but slower swings. One clean hit cuts anyone down. Six worlds of groves each add a rule (tall grass, blade-stopping stones, falling fruit, night, a closing thorn ring) and end with a boss, plus a Daily Grove and the One Life leaderboard.
Eat glowing dew and cut down rival sprouts to grow through twelve forms, and be among the biggest in the grove at sundown across six worlds that each add a rule and end with a boss. Each form has a longer blade but moves and swings slower, and one clean hit cuts anyone down. Drag anywhere to walk, tap Swing to strike and Dash to burst away; with a mouse, steer with the pointer, click to swing and right click to dash.
