In addition what has already been mentioned about bull almost immediately running off the edge of the world if it isn't steered, I'd also highly suggest increasing the amount of time that the instructions text is shown at the start of the game. I literally had to restart the game 3 or 4 times before I was able to read through all of it. Also, the first bullet point of the intro text should tell the player the controls, not the bottom one. I don't mean to be harsh, so I hope I don't come across that way. I'm just trying to provide constructive feedback. :)
