About Square Jet GameSquare Jet is a 21-stage jetpack flying game. Tap the W key or the up arrow key to fly, holding them in to ascend more quickly. When you release you descend. Move left by pressing either the A key or the left arrow key. Move right by pressing either the D key or the right arrow key. You have a limited amount of jetpack fuel credit you fly with & it gets replenished each time you touch the ground. To make efficient use of your fuel it can make sense to tap or pulse the fly command rather than holding the button in. Avoid touching any of the red hazards or falling into the lava. Collect up to 3 yellow gems on each stage, then pass through the portal exit. Orange walls or platforms can be walked on, though disappear when you collect the key. You can jump on the triangles & they act like trampolines when you hit them. This is a JavaScript web application which uses cross-platform mobile-friendly HTML.
