If you played the game and the whole screen was blurry or even wibbly-wobbly like the fire on the right... or if the plants weren't gently swaying like young optimistic teens at a school disco pontificating on whether Britney really did want to be hit one more time then we've got news for you!
It was a cunning plan to remind you that you were playing with OpenGL on an NVidia card. Now that's done we've fixed the bug, I mean wibble.
We also patched a few particles that were naughty and won't be allowed out to play again.
Have fun Exploring and Destroying.
