Just okay for me
Very very challenging
Difficult. Game can't be saved if interrupted - you have to start from the beginning. The shapes relating to the coloured stars are needless and therefore misleading
Best so far All puzzles logical. Only negative is items had to be collected and used in a particular order so there is a lot of searching over and over in the same area rather than picking up an item and finding a use for it later eg the screws aren't on the factory floor until you have found the saw, you can't use the candles as soon as you realise what to do with them you have to wait and keep going back to them etc. which gets a bit frustrating.
If you have to watch the video walkthrough, or have to stop and resume play later, you have to start from the beginning all over again! >:(
