Woot, I got the imp! The last message was funny xD
It managed to be difficult without being too frustrating, and very fun at the same time. The level design was pretty good too. The only problem is that sometimes (especially on Skater level 20) my vision would get completely obscured by a block and I would fall :(
Anyway, nice game, 5/5 and fav'd.
This game's rating got hit hard because of its difficulty... a shame. Most people these days can't seem to realize that challenge is much of what makes a game good.
Woot, I got the hard with exactly 100. Throw it at about a 15 degree angle and wait until you get to about 25 altitude, then use the first two fuel tanks. This should get you to around 90 altitude. Level yourself out, then keep yourself horizontal. When you get heavily slowed down by a jetstream, use about a quarter of a tank to boost your speed a little and level yourself out. After a few tries, you'll get it.
The game is great and the music is excellent, but it gets 3/5 because of a glitch. When I play level 17 (it only seems to be level 17 for me), a block will end up inside another block somewhere at the end. And no, it's not just me confusing the layers, I've examined it thoroughly.
