Adjust your size to reach the goal! Tap the on-screen Arrows to move. Tap the UP arrow to jump and tap the DOWN arrow to crouch through a small space.

Every level contains at least one yellow block you can hit from beneath to get an item. Your first item will be an ice cream sundae, which makes you taller! There are a variety of other powerups you can get from these boxes such as the double jump ability (this allows you to tap the UP arrow twice to do two jumps), the dash ability (this allows you to press the lightning bolt to dash forward), the flying ability (this allows you to press the UP arrow to fly up and then hold that button to glide downwards), and the snorkel ability (this ability gives you a snorkel to swim through clear waters with ease).

Along your journey, you'll have to overcome obstacles and enemies. Jump on enemies to destroy them; if they hit you, you'll shrink! Avoid obstacles like spikes and green water. There will also be gates that require you to solve a puzzle. You will also find grapple hooks to help you go from one platform to the next. When a cursor appears on a grapple hook, tap the white cursor button in the bottom right corner of the screen to grapple onto the hook and hold the button to stay hooked! Once you're ready to let go, release the button.

Red flags are checkmarks, so if you fall off the level or get hurt by an enemy, you'll start back at the last red flag you touched.
