My favorite platformer before I owned any "real" platforming games. I played this as often as I could in the fourth grade, whether I was at home adhering to strict screentime limitations, or in the school computer lab when it was permitted. Even after beating it once, I replayed it over and over, trying for no-damage runs and attempting to collect every last nut. I remember one day, a few of my classmates saw me playing it and initially teased me for it, but when they sat down and tried it themselves they found it as fun as I did. A true classic, as far as web games aimed at kindergarteners go... I'll never forget it.
