If the inferno background was the harmony background, only red, and the harmony background was the inferno background, only blue, it would make more sense.
Jirekianu, none are impossible to ace. Some can be aced using two balls. I've aced them all and you can go to my profile and look at the badge to see for yourself.
I just got 25 to 7 seconds (that's how i got the badge). You have to burn the boxes first otherwise you'll be waiting for too long. Use about half the bar of power and aim at the middle of the boxes. You want it to hit the boxes, bounce out, light the torch, and bounce back in. Hopefully you'll land in the middle on the burning boxes. Once they burn away you'll fall down and light the others. What's your total time btw?
Oh, wait now I remember how I did 20. There are three boxes around the purple ball. You want to aim for the area right under the box that's sticking out (the left box). You want to bounce off the top of the platform and then hit the bottom left corner of that box. This will make it shoot straight out to the left and hopefully light the first torch, bounce back, and light the one under the platform.
My computer was lagging like hell. I didn't do anything to bring it up. I can't reproduce the glitch. For 20 use two balls. There's a bunch of ways to do it, but the main idea is that you have to hit the corner on one of bottom pillars just right to make it shoot under the platform and light that torch. Then you really quickly shoot at the top torch. I can't remember my exact technique. For 38 you have to use a low power: about half the bar. Shoot it directly at the top torch and hope it bounces into that hole right above the bottom torch that you need to light. Both of these will probably take several tries.
nugget, I have these times (my total time is currently 161, lol): 20; 4.295 - 25; 8.587 (but could go down to 7 if i get it jsut right) - 35; 12.462 - 38; 7.373 - 40; 3.463 Level 40 glitched for sure. I could only get it as low as 9 seconds. I tried getting it lower and then i got some lag spike, lol.
For level 4 you have to shoot up for the ball to gain enough speed to go down, light one torch, bounce back up, and bounce to the other side to light the other torch. Level 4 is one of the hardest to ace, so if this isn't working don't give up hope. It will work, but you have to get it right on the mark. If it's off by a little, it will get stuck down there.
quindraco, for level 4 you have to shoot up in the air to get enough speed to go down one side, bounce back up and go to the other side (it is VERY hard to do). For level 33 you can use two shots to ace it (same for 35 and the secret level "A").
