You play as a brave fox knight exploring sky isles suspended in the clouds. The game asks you to navigate treacherous floating platforms, avoid or defeat enemies by jumping on them, gather glowing gems along the way, and ultimately face down a powerful boss. Each island grows more challenging, testing your timing and platforming skill.

What it does

You control a fox knight who jumps between platforms made of grass and clouds. Slimes patrol the islands—jump on them to stomp them flat. Collect turquoise gems scattered across each level to build your score. Three islands lead you toward a final confrontation with a purple boss creature. When you take damage, you lose a heart; collect hearts to stay alive. Reach the flag at each level's end to advance.
