I think the user interface for flash Sonic is clean and simple but quite life less. For example none of the selected buttons that are clicked light up or show any indication that they are selected, which is one feature that the interface could use to give it some life. Other than that i think the interface is very simple and easy to use.
Flash Super Meat Boy has a very bland interface from the get go, every thing is very grey. But a good point about the menu and interface is that when you hover over something it will high light the option.
Flash PacMan has a very good interface in my opinion. The layout and content is very easy to use and read, also the icons in gameplay are all simple and easy to understand Plus all at the bottom of the screen so that it doesn't interfere with the game or distract the player.
