Welcome to cave hoverboarder. Use the up arrow key to go up and you will automatically go down. It is like flappy bird.There is a store that you can buy hoverboards at. If you win, you will have to equip your hoverboard again. Buy your hoverboards in order or it won't work. You have to click the green flag again if you go into the shop to close it. Don't touch the walls or the red letters in the messages. Try to get to the end. You are trying to get out. The cave has collapsed behind you. You have to go through the center of the earth to get out. Escape and have fun.
I got the idea and kind of like the landscape from Aiden12503
