I already said this stuff in class, but I figured I'd type it here so you have a record of it.
I like the game a lot. I like the music and I like how the difficulty ramps up. I also like that carrots sometimes spawn in spots where you'll have to fall a little to get, so there's some decision making as to whether or not to go for them.
For notes I'd just say make it clear that you have to jump to start the game, but again it's not that important. I think most people would figure that out anyway.
