How to play: It's simple, really! Just use the arrow keys to move, and try to collect as many red gems as you can in 100 seconds! But try to hit as few blue ones as possible! Blue gems work like this: when you hit one, it gives you more points depending on how fast you're going. It also makes you gain a bit of speed. How red gems work: They lower your speed and take away 10 points.
When it's times up, the Jetpack Man will fly towards the edge. Then you finished the game! That's easy! Enjoy it!
