Thanks a ton for the suggestions!
Will keep all of this in mind for the future! Ctrl Z sounds like a great idea, and I can definitely think of interesting puzzles with it. As for points 1,3,4 and 5 those are all stuff we should iron out in a future release. Thanks for pointing them out.
We can't answer 6 for... reasons ;)
But you did bring up a valid point of there being some levels where we have a few bugs pertaining to the clipboard, simple overlook on my part haha.
Once again thanks so much for your feedback :)
