This would be a good game if it didn't establish rules that it then broke seemingly without rhyme or reason. In the floating chasm with the rock and two ice blocks, you can't land on the ice blocks like platforms. In the level where the crystals slowly grow and you need to follow the trail, there is a single ice spike you need to jump on to lift you to the next path, even though you were informed that jumping on ice spikes is bad. This game is chock-full of trial-and-error gameplay, and the arbitrarily added restriction of being unable to backpedal (why??) only makes it worse. This game might have been better if you invested more time in areas besides the novelty value. And frankly, it's the kind of novelty I'd prefer not to experience. 2/5.
I got my ball in on the last remaining hit in the first level, then on level 2, I missed the hole and it was game over. Even though the game said I had 3 hits left.
I once got 1 correct digit and 2 correct position. How is that even possible? Plus, I don't think there's an algorithm that lets you deduce 3 digits with 10 possibilities each in 6 moves. Therefore, it's all luck. But I'll give you a 2 for effort.
