very easy to beat, thus very entertaining to play. nice for children i assume. low replay value.
if the dolphin tells you of a treasure you cannot find, i assume there is a cavern with an entrance somewhere else. use the map (hardly documented - see inventory.)
kudos. desining these levels must be very hard. nevertheless most of them have just a single way to solve them, which is very obvious. thus the gameplay is not really enjoyable. towards the end, some level rely on borderline effects of the game engine (be at the right pixel, turn to the exact degree and pray the timing is right) to be solvable. not very nice such things. thanks anyway. a welcome distraction - apart from the dizzyness. very innovative.
