"I enjoy video games a lot so I made one," Ryan wrote on his blog. "I feel nervous about my game ... it's rather simple. It's called Angry Face! This is my version of Pong. I wrote the game but my 4 year old brother helped me with sound and testing. He really likes the game. This is the very first game that I've created and I want to make more in the future. I hope I get a good response and that everyone likes it."
Ryan also mentions that he made a "grandma mode" difficulty level at the request of his grandmother, as well as an "expert mode" difficulty for those looking for a challenge. You can play Angry Face in a web browser for free, so long as you have the Unity Web Player extension installed.
