Ahh thank you for bringing those bugs to my attention! It seems there was a problem with the build as it was fully playable in the editor. I made a new project with the updated version as I accidentally deleted the files on the submission one, if you wanted to play it how it was intended ^^

I worked on puzzle game with sliced images few month ago, and we cannot have a perfect random on the slice location because of this issue (which is super annoying!) we have to predefine the position of the piece at the diagonal of the piece you remove (on the bottom right)
Also I liked the last puzzle where we had to move instead of click, wwas very smart.
