Unity has apologised following the furore around its disastrous plans to charge developers when people download games made using its technology.

The plans prompted an enormous backlash from developers across the industry, and threw up a multitude of questions around how the new policy would work in practice - answers which Unity belatedly scrambled to work out itself.

This morning, Unity said it was sorry for the "confusion and angst" its changes had caused, and promised it would make unspecified "changes" to its plans.

But despite days of confusion, Unity said it still needed more time to confirm what these changes might be - and the suggestion certainly seems to be that these changes will fall short of the full U-turn developers have called for.
