I have managed by some miracle to reach the blue crystal in Tsunami and have been transported to an area with boxes and upturned boats. At the end there is a crystal by the portal. I am standing on the last but one box but cannot reach that box in one leap. How do I get this jump and ultimately the crystal. Thank you.

According to my sources you should be able to hop across the boxes all the way to the end. Some of them are a stretch but still should still be reachable with well balanced jumps. The boxes on top of the exploding boxes at the end leaves you with no time for think. The level is diffiult, but be assured that there is no secret trick. You just need to practise your jump technique and before you know it you will get that hiddne clear gem.

Good luck.
