On Release challenges you to get the highest score you can. Just don't go tapping at the screen like you would with any other 'runner'.
On_Release() is all about getting the functions to run for as long as they can. Avoid all of the bad blocks of memory or you'll cause an error and bring up the dreaded BSOD.
Press down on the screen to have the top block jump and let go of the screen to have the bottom block jump. It's as easy as that.
