Enjoyable but it tends to freeze after senerios are completed

At least it saves your progress before the freeze, but then it will often become non-responsive with the rotating sideways unmbrella of doom. Purchased it today and have experienced 7 freezes so far... the only app on my entire computer that does this by the way. Again, at least after relaunch I did not lose my progress, but this would have been a 5 star game if it was more stable.
