Left arrow moves the car left. Right arrow moves the car right. Catch Gobo avoid the bombs.
I made it so that when Gobo goes below a certain height it makes you lose a life. I also added "delete this clone" blocks instead of "hide" blocks. This is because there is a clone limit of 301, so you can't have any more than that on the screen at any point. When you hide a clone, it is still there, and can be re-shown. So to truly free up some memory for Scratch to use, you have to delete the clone. Finally, I'd like to suggest (i.e. I didn't add it) you put all the arrow key controls into one forever loop (if <key [up v] arrow pressed> then). This is because the hat blocks react to key *presses*, like when you type on a typewriter. When you hold down a key like "t" you have to wait a short time for it to write one character, then wait a bit more to start writing a long row of them: ttttttttttttttttttttttt. On the other hand, the <key pressed> block reacts immediately when you press the key, and keeps going as you hold it down. Hope this helps :)
