Thanks talrnu, in the next few days I'll be uploading the next version of it with a few updates. Like:
The glitch where you can just move it, let it go anywhere and it stays there is now gone.
There's 30 levels
And I'm currently working on the cookies function where when you've finished a level is saves it so you don't have to complete it all at once!
Hope you enjoy it!
Thanks and yes I have seen this bug and will fix it for the next version, just try and move the pieces where they should go and it shouldn't be a problem
