You think Level Four is hard? Wait till you get to 17! 
(Although one of the upper levels was really easy… 12, I think?)
How do you use the passwords? Think “button”.
Just a thought: if you can’t beat level four, you’ll probably have a harder time with the upper levels – by using the passwords, you’ll be able to see them, I guess, but if you can’t solve them…
I agree, level 17 is hard. I skipped past it because I needed a new level to look at (20 mins straight of that level was too much) but level 18 is also complicated.
i did press a button! it says level password and i write the password and it says loading but i don’t go to the next level!!! 
Sorry, DrawingBoy, it works for me. shrug The site is a little slow sometimes, though…
[Note: This was not intended to be snide.]
which button do you press?
I don’t see ANY buttons to press.
(I’m still stuck on 8.)
Drat! Still having trouble with 16!
Holy mother of crud!
Like I didn’t have enough little diversions keeping me from getting the laundry done…
I zipped up to level 13 and think I figured it out but laundry beckons… must… pull… away… from… game…
Need another hint?
WARN this biotch.
The double mirror is the first one the laser hits.
Level 17 right now, have only spent a little time there so far. Level 8, and level 12 were what killed me. As I play it, my husband is on the laptop in the living room playing, and my friend is also playing and we are sharing hints over msn messenger. This game is addicting!!
Jeeves
17 is killing me. I’m ready for a hint if any of you geometry wizards are willing to give one.
level 16 is kickin’ my ass!!!1
I’ve breezed through up until i hit level 16. I’ve looked at the hints and still come up one bulb short. Damn it, I don’t want to skip ahead.
Ah!!! Got 16 finally! And frankly the hints were nearly misleading. Here’s my hint on it, and it’ll probably make it alot easier.
16: Don’t hit the 2 in the middle first.
[through clenched teeth]I can’t get past 11. I have all but one stinkin bulb. I will go mad if I do not solve it soon.[/through clenched teeth]
I hate to say this, but:
Please help.
I went back to 16 and took a screenshot of it almost solved. Email me if you want it. I don’t think I can give very good written hints.
Mogwei22 I’ll go back to 11 also. Email me if you want a partially solved screenshot. It may take me a while to remember how I did it though so give me a few minutes.
I’ve gotten to level 18, but now I must go to sleep.
On level 17, and I’m convinced double mirrors are the spawn of the devil. For some reason they are the only piece i can’t visualize easily.
I’m not saying I’m asking for a hint here…but you know.
I’m going to kill whoever invented this game.
Well, I guess I need to make these hints a little more obvious then. All my friends who I got hooked only wanted semi-hints. Here we go, for level 17:
W
A
R
N
I
N
G
?
All coordinate values are in (x,y) format with the bottom row 1 and the left column 1.
The splitter belongs at (9,2).
The bulb at (6,10) needs to be hit by a double mirror at (6,5).
Well I quit with level 18 and 19. I’ve been looking at them too long. I can get em both to one unlit but that’s it.
I also discovered that there are multiple ways to solve level 20. That is, unless we’re supposed to have extra mirrors after beating it. Either way, onto level 21.
