giaks provided me with saves for the other levels so I could at least try them. They are all difficult and I didn't manage to complete any additional levels that came with story. There are some new mechanics added in the later levels and a new type of level altogether later. One that involves memorising colour patterns, unfortunately I couldn't work out how to advance it correctly as completing the sequence didn't seem to start the next sequence, I would wait a bit enter another one and then get it wrong and then it would progress. So I feel that it needed more instruction about what to do.
Other than that I feel the review is still accurate.
