I played this game a lot as a kid and could never beat it until now! This game, and its two sequels of course, are among the best games in Flash History.
It's a really easy game and short if you're good, but there's something super addicting about continuing to play until you get that next glider or to glide a few feet more than you did previously. If you like this game I'd recommend ones like "Flight" (which is about a paper airplane) or "Fishing Girl" (which has the sort of slow upgrading style of gameplay that this game thrives on). Happy Gaming!
