What is the Platform adventure game?
Platform adventure is a side-scrolling run-and-jump game you play in the browser with nothing to install. You guide Orbi, a small space explorer, through six levels in three worlds. In each level you collect stars, look for three hidden gems, dodge enemies and reach the portal. It works with a keyboard, touch controls or a game controller.
How to play
- Tap Start the adventure. The map shows three worlds with two levels each. At first only the first level is open.
- Pick the level and go in. Orbi walks left and right and jumps. Hold the jump button to jump high. Let go early for a short hop.
- Grab the shooting stars along the way. Each level also hides three gems. They sit up high, under platforms or off the main path.
- Jump on top of an enemy to defeat it. If it touches you from the side, you lose a heart.
- You start each level with three hearts. Spikes, shots and enemies take one heart. After a hit, Orbi blinks and cannot be hurt again for a moment.
- Falling into the void also costs a heart. In that case Orbi comes back at the last beacon you lit. A beacon lights up when you walk past it.
- Use the scenery: the spring launches Orbi very high, the moving platform carries you across, and the platform with gold stripes vanishes shortly after you step on it.
- Reach the ring-shaped portal to finish the level. The next level opens on the map.
- The second level of each world ends with a boss. The portal only opens after you jump on the boss the right number of times.
- If all three hearts run out, the level restarts from the beginning. When you beat the sixth level, the lighthouse of the stars shines again.
Controls
- Keyboard: left and right arrow keys, or the A and D keys, to walk. Space, the up arrow or W to jump. P pauses and resumes. M goes back to the map while the game is paused.
- Touch: on phones and tablets, large buttons appear. The two arrows on the left walk. The green button on the right jumps. The middle button pauses.
- Game controller: D-pad or left stick to walk. The ✕ button on a PS5 controller or the A button on an Xbox controller to jump. Options or Start pauses. The ○ or B button goes back to the map while paused.
- With all three, the jump goes higher the longer you hold the button.
- On the level map, move left or right to pick the level and press the jump button to go in.
The three worlds
- Crystal forest: the training world. It has patrollers that walk back and forth, hoppers and the first flyers. The boss is the crystal guardian, which falls after three stomps.
- Glowing caves: here come the shooters, which fire slow balls of light, and the carpets of spikes. The boss is the big lantern, which also shoots and falls after four stomps.
- Cloud city: there is almost no ground. The chasers show up and make a short dash when you get close. The boss is the gale, which flies, dives and falls after five stomps.
Tips to play better
- A short hop is as useful as a high jump. Under a flyer, just tap the button.
- When you stomp an enemy, hold the jump button. Orbi bounces much higher and reaches new places.
- On a moving platform, wait until it comes close before you jump. There is no hurry.
- The shooter flashes white before it fires. Jump over the ball of light or wait for it to pass.
- Against the gale, keep moving while it shakes in the air. When it lands and gets dizzy, jump on top.
- Missing a gem? Look up near the springs and under the platforms. You can replay any open level: the game keeps the gems you already found.
