Hey guys I love this game it's awesome! There are a few bugs though, it would be really great if some updates were released considering this is a paid app.
Here is my experience playing on the iPhone 5s.
1. The game does not save progress in Main Puzzle mode, on quitting the app and opening latter my progress has disappeared and I'm forced to start from the beginning levels. This is really frustrating!
2. It is not possible to play any community levels any time I try to play or edit one I get "an unknown error has occurred".
Thanks for an awesome app guys first Apparatus now this :) But please get some updates / fixes happening.
