Edit: Now that my issue has been resolved I'm happy to bump my review to 4 stars.
I really enjoyed the first Tinker Island and I want to enjoy this one. But everytime I close the app or minimize it for to long the game freezes and resets back to the start of the game but you can't do anything. I all ready reported the bug but this bug makes the game unplayable unless you never close it. Hope they fix it soon so I can play it properly.
