The key to my heart doesn't seem to work. I've got the xx and I'm changing the tabs whilst holding it, but it's not going onto the kong tab.
As for zoom: Ctrl + Scrollwheel :)
SPOILER:
To get the lightning power, you need the parachute (glider) first. After you've got this, climb up to the top of where the several pillars with vines are and go to the NPC that says "I wonder what the point of these pillars is?" Then jump to the right but parachute into the next area. You should find yourself on a hill with thunder blocks, and the thunder ability is in the middle :)
The game won't pause whilst the game window is maximised. So you can't have other tabs, but you can have as many things on your computer running (including other internet windows), except they can't be in full-screen/maximised mode.
SPOILER:
The secret:
After the voice tells you not to touch the statue, do so. Then fall down the tunnel on your right. At the bottom, instead of continuing the path right; go left, and walk through the spikes. I'll leave you to find out what is there :)
Impossible Badge: Die three times
You can actually play again, but it means practically destroying all you save game data on kong and spending some time deleting all the moshi folders.
