I did hear some audio comments being made after I did jumps, but it was commentary on how you did, such as "Wow, that was almost impressive", and only after I had done bigger jumps. I did not hear any kind of instructions at the start, nor as I progressed telling me in advance how to do things.
I understand running out of time for in game instructions, but you can add them to the web page for the game. Uploads are locked during voting, but editing your page is not, so you could still update it to help others who play.
