Fun little game, clean and easy to pick up and play for a few moments.
Maybe it's just because I keep dying before I get high enough (73k is my highest score so far), but does something happen when you hit a certain point value? Perhaps a change in scenery? I keep waiting for something to happen.
The only way I've found to get out of the High Scores view is by hitting Return, while Return or (sometimes) a click will exit the How to Play view - might want to make that more consistent. And for some reason neither Command-H nor Command-M works, yet selecting these options from the menu does.
