Click or press space to go up and let go to fall. Dodge the meteors and collect the coins. You have three lives represented by the icons in the upper left corner. Once you die you can click vehicles and select different vehicles with the arrows to drive. You can also buy new ones with the coins you get.
Music is Strobe and Ampli - "Chipset Sunset" and font is Minecraftia Sound effects made at http://www.bfxr.net/ There are currently only two vehicles, one you get already and one you can unlock for 10 coins which ascends faster, but more will probably be added :)
