Thanks for giving me credit
need soultion for level 59 help!!
I need solution for level 75!!! Please help!!!
Place the first arrow just after the second turnstill pointing up & right..
)
The second arrow is just under the round rubber bit.
This gives the ball enought speed to bounce off the rubber in to the wall to break it. I havent got 3 stars yet.
But at least I finished all levels.
Is there a way to clear level 79?
Yes, please give me the solutions for level 79 -.-
level 79, three stars:
the first arrow you must use is “up”, put it close to the cat.
then you must use left arrow to bounce the ball against the wall.
after that use down arrow against the glass, but without break it, just touch the corner.
when the ball hits the hill you must try with the right arrow.
i´m sorry for my english, i hope i have cleared the question.
Hi, level 69 really doesnt work for me, i can’t pass the turnstile :/ Have you another idea?
IT’S OK !!!
it took me ages to do this one even with the guide. i kept focusing on shifting the 2 up arrows, when i just needed a slight adjustment on the right arrow
this guide is spot on, and has helped me avoid hours of frustration, thanks guys
It won’t let me see 42 thru 70
Can you see it now? I’ve been updating the post.
Some of those levels doesn’t work!!!!!!!
All of them should work. Can you name one? I can post an alternate solution to that level.
I know 61 doesn’t work. I’ve been thru all of them but I was just checking yours out and 61 does not work. It doesn’t even show the other button you have to push. I have all 3 stars on all the levels. I’ll sure be glad when they get more levels updated. I’ll try to go thru others and see if they all work for 3 stars later.
I got it to work the other way. Sorry I didn’t read down far enough to see the other replys. sorry again.
i need help on 61
thanks for the guide. ^_^
but 61 seems to not work for me – i place them all in the right places and i get it through the first gate but then it’ll just bounce once and disappear and restar the game.
(just to make sure, only one of the buttons should be pressed right?)
This one is a three stars solution. If you look closely, you can see a teleport above the black area at the top left. The ball should get there and then appear beside the black cat.
If you want a simpler solution then you must press both buttons.
Do you need a screenshot for the alternate solution?
I had a feeling that it had something to do with the teleporters…
I kept messing around with them and eventually got it to work… Thanks. ^_^
I cannot get level 48…that solution doesn’t work…does anyone have another?
Hey, I just posted an updated solution for level 48, scroll back and see if it helps.
Number 75 is causing me problems. I have copied your suggestion, but I am no further? Regards
Worked level 75 out. U place the arrow pointing to the right after the second spin wheel, The ball will then rebound off the green ball smashing glass panel,
No, the ball shouldn’t touch the green ball. It should fly straight to the glass.
I hope that helps.
Level 54…I can get the ball through the teleporter and it comes out at the black cat but zooms off away from it. How do I solve this?!
Can’t get through level 44
Yeah. That was a wrong one. See the updated solution.
Level 69 doen’t work for me!!!! Help please???
Just keep trying, that’s a tough one
help, level 47 doesnt work for me
Same as above. The walkthrough is correct, I followed it twice.
level 80 is wrong. it doesnt even get 3 stars. does anyone hav a better solution?
Just updated level 80 with 3 stars solution.
Help! I need solution for level 52!! The one here doesn’t work!! Black Swan!

Same here! – Nice Job!
i need help on level 53 it won’t work!!!!!!!
LVL 71. I can only get one star (518 points)
Anyone know a better way to get 3 stars?
Level 61 Won’t Work. I’ve Tried Sevral Times On My Own And With Help. So please I think it’s wrong!!!!
this one took my full day.. finally found the walkthrough…
HELP with #36 please. It just wont work for me. The ball won’t make it over the last ridge. Any suggestions?
Just try to bounce off the platform while it’s moving to the right.
cannot get thru 75.. tried the solution given
the ball doesnt break the glass nor does it reach the second arrow
Ignore the second arrow. It should go straight to the top part of the bottom glass and break it. If your ball jumps too high, move the arrow a bit to the left.
can anyone help me with level 74
Great Game I Saved All Images To My IPhone So I Passed Most Levels With Either Two Or Three Stars Great Walkthrough!
I can’t break the glass on level 75!
Hey
i though u might like to i know i found an easier way on lvl 32. To get the highest score on it, u have to get 540 right…well i got 615 
Step 1: Take the “up” arrow
n put at the corner under the horizontal bar with the little up arrows on it. U will have to pull it down a bit so the ball can reach it!
Step 2: Take the arrow that is at an angle pointing in a northeast direction n put it in the corner just above the horizontal bar with the little up arrows. The ball should go over the rock wall with the button on it, bounce once on the top (you will see a little flash up there) n it should fall on the other side of the wall to the black cat!
Step 3: Depending on the exact positioning of the arrows, when the ball goes over the rock wall, it may not make it all the way to the cat…but if you put the arrow pointing to the right on the ground right next to the black cat n it should go right to it!!
I hope you can get it!! Good Luck!!
32 I have 769 on this level
trap door glitch required and glitch through glass wall too 
how do u do it mate, pls teach me?
see this

Lvl 69: although it doesn’t seem to work as positioned above (exactly!), I found that there’s enough slop in the code that the results can vary very slightly. One out of ten times or so the ball would move past the turnstile without my moving anything.
Thanks for a great resource!
Where do I find solutions for levels 81-90?
