Huh. This brings back memories of a particular flash game everyone played on their school laptops back in middle school. I do not like having to do the whole thing over again if I fail late in the game. Make the reset option only apply for the level you messed up and have a separate option to restart the whole thing. I also took a while to figure out the whole "press down to make yourself bounce higher thing". That probably should be posted more clearly on the third level where it's required to progress. The graphics, while simplistic, would probably look better with some kind of visual flair or some kind of artistic theme. I dunno, make one up! I say, work on these things and make an HTML5 version to put on browsers.
