The first 'world' you experience will be familiar if you've used the original Bloom. However, the remainder all introduce new rules, sounds and visuals. It's like an album versus a single, according to the creators. You can also expect a "simplified" interface versus the original.

Eno and Chilvers haven't nailed down the iOS release date, but note that the Android version will be available December 7th. You'll want to act quickly if you like the idea, whichever platform you choose. Bloom: 10 Worlds will cost $5 (£5) if you either pre-order the app or buy it on the release weekend, but it'll climb to $8 (£8) if you wait. That's not trivial for an app you might not use forever, but it could be justifiable if you're an Eno fan, an art enthusiast or just interested in some mobile app nostalgia.
