Very good playthrough, and great feedback. Thanks! I might steal your idea to have cows floating around in the background, screensaver style - should be very quick to implement ;)
The levels do get harder as you progress further, but with the current level randomization it can be hard to notice. You did reach the cows, though, which are the last enemy (chicken, pig, cow), so you did cover all the content in the vid.
Also: liked and subbed on YT ;)
