That is the tutorial and you press the 'Play' to move on to the Level. Sorry I didnt make that more clear! :)
Oh, I thought it was just telling me to play, haha. I beat it already and found the secret pass too, won with 21 carrots
Well this is really helpful for the next game I make, I'll be very clear with my GUI xD you're awesome for finding the pass! I hope you enjoyed :)
