andy ColonelFazackerley I have a vague policy of avoiding levels which require large numbers of blocks, except for extremes, because of poor performance on mobile. I'm sure I haven't stuck to that though.
ColonelFazackerley andy Only needs 16. I am sure there are several in the game already that need more. We could make it smaller, by reducing the height of the red zone and lowering the block.
Tom I think it might need more if wind was fixed. Anecdotally it felt like the top of the tower wasn't blown about as much as the bottom. Edit: With some testing it looks like only the middle of the level experiences wind.
