Okay, I admit - I’m stuck on 10. I went beyond and solved some of the others but I’m ticked cause I didn’t get 10. Help!
Please. Solution. Please. God Almighty. Please.
Tibs.
Okay, just got 10 - now back to 18. Sheesh.
Tibs.
wellfor the love of God, how did you get 10? I have breezed through up until now dammit. 
Nevermind.
Geez, all of these seem so obvious when you are done…
Level
10
Spoiler
Ahead
Go up and around the edges.
17, on the other hand…that level hurts… 
Someone please help on 10.
The best I can do is the following:
Go RIGHT across bottom of screen
Then UP
Then LEFT across top
Then 45 DEGREES DOWN/LEFT into the room
The SPLIT UP/LEFT and DOWN/RIGHT to hit all the bulbs in the room
However, this leaves one bulb and two unused mirrors!
::Pulls hair out::
OK, my hints for level 10.

Go all the way up to the top from the start.
The splitter is the last piece hit.
I don’t know why I had trouble with 17 last night. I looked at the coordinates given, and those are the exact place I had them last night and didn’t see the solution, this afternoon I got it the first try after placing those two pieces.
On to try 18…
Well, 19 is killing me now…damn double mirror.
I’m also stuck on level 6 but I have no cold medicine to blame. I am just a moron when it comes to these spatial type games.
Woo-hoo! Just got past 6!
Could someone gimmie a hint for lvl 10?
Speaker, do you need something more than the several already given, or did you miss the ones here?
Hints for 19 would be appreciated.
Gakk! Now I’m stuck on 8!!
I think I’m going to need an all out solution for 17. Even with the placement of those two pieces. Anyone?
OK, first I just solved 19, but I think I might have used a loophole in the intended method. This might or might not be considered a hint, so I’ll do the standard warning:
Apparently as long as the laser hits the last bulb before it hits a bomb, it won’t explode and end the game. I spent alot of time trying to solve 19 thinking i could only attack the last bulb from a couple angles, but it turns out that even though the laser goes through the light and hits the bomb, you still pass teh level. Odd.
Gut, here’s a really thorough explaination, I won;t outright place the pieces, but you’ll definately see the solution. Only read this if you have absolutely given up on the level. You’ll kick yourself 'cause it really inst that tricky.

OK, place the double mirror and splitter as have been stated above. One half of the splitter goes into that little room and you use the refractor to spin the beam around and hit the bulb on the way out. That beam hits the double mirror to light the topmost bulb. Use the remaining mirrors to zig zag the other half of the splitters beam around to light the bulbs near the laser. The leftmost bulb is the last one hit.
Outright enough?
OK… I finally got 10
#10 SPOILER SOLUTION BELOW!!
- UP and “OUTSIDE the box”
- RIGHT
- DOWN past the bulb
- LEFT
- UP
- LEFT
- 45 Degrees DOWN/LEFT
- SPLIT
ENJOY!
Damnit, one mirror short on level 21.
Thank you Omniscient. It was getting the beam back out of that little room that was killing me. I’m not going to try 18 until tomorrow least I go insane.
Nice to see I wasn’t the only one. 
I have the feeling I’ll be using that complete explaination myself in a bit.
