Nice platformer. Eleborate level design. Intro. Fruits. All there. But couldn't you scale it up a bit? My eyes are too old for such small windows. Some background music could also improve the game feeling.
may I ask what exactly you asked me to increase, content? or graphics?
Graphics. What is your screen/window size, 320x240 ? Scale it at least by the factor 2. Just a suggestion, of course.
ok! THk you for idea!
