Jumping Fox

You run and jump through a side-scrolling level until you reach the lantern at the end. Along the way you stomp enemies, collect coins and hit crystal blocks from below. You have three lives: falling into a gap, touching thorns or running into an enemy with no protection costs you one.

The berry makes you bigger and tougher: you can take one hit, and you can smash ordinary crystal blocks from below. The feather lets you double jump in midair. Every hit you take removes the berry first and then the feather, and once both are gone the next hit costs a life.

Beetles walk back and forth and you defeat them by jumping on top. Bumblebees fly in a lazy sway and can be stomped too. Hedgehogs alternate between walking and curling into a spiky ball: you can only stomp them while they walk, and they shake before they curl up. Chaining stomps without touching the ground multiplies your points.

You start with three lives and earn another for every 100 coins. The beacons halfway through a level light up when you walk past them: if you lose a life, you restart at the last lit one with the time you had left. If you run out of lives, the game ends and you can retry the level.

Yes. On touch screens, left and right buttons, a “Run” switch (tap it once to turn it on and again to turn it off, so you do not have to hold it down) and a big jump button appear on their own, and you can press several at once. If you want them on a computer, turn on “On-screen controls”. The game pauses by itself if you switch tabs.

Yes, only in your browser, and nothing is sent to a server. Each level you clear unlocks the next one, and your best score and each level’s record are saved. If you clear the site data, they are cleared too. Add ?seed= to the address to replay the same game.
