Product Launchers have been activated and World of Goo for iPhone is slowly oozing out all around the world! If it’s not available in your region yet, just give it an hour or two. World of Goo HD is now universal so you can play it on iPad, iPhone, and iPod Touch as soon as you buy/update. World of Goo (non-HD) is playable on iPhone and iPod Touch.

Also, David just told us he’s putting his adorable Goo Ball beanie hats on sale to celebrate this occasion… 50% off until April 20!

It’s official, World of Goo for iPhone will launch this Thursday, April 14! It will be priced at $2.99 (and equivalents in the rest of the world) but will be on sale for $0.99 for the first 24 hours after release.

At the very same time, we will release an update for World of Goo HD (still $4.99), which will make it a Universal App.

This means that if you want to play on both iPad + iPhone/iPod, you should get the $4.99 HD version, and if you want to play on your iPhone/iPod only, you should get the $2.99 non-HD version. Remember, this game requires an iPhone 3GS or iPhone 4 or 3rd generation iPod Touch or newer.

Warning: We have discovered a strange new character who mysteriously appears after the end of the game.  This new character seems to appear only in the iOS versions of World of Goo. But upon further investigation, there seems to be a good reason for that.

The Goo Balls are restless. I’m sure they are attempting to communicate a big wet thank you to all you fantastic fans out there who have supported us through the years with praise, excitement, and the spreading the word.  Thank you all!  Hope you dig it.

FAQ

Q: Do both versions support retina displays?
A: Yes, both versions support retina displays, and should look identical. Update: Some players are reporting lack of “retina” support. We’re investigating. Thanks for the feedback.

Q: Pinch-to-Zoom?
A: Yes, World of Goo supports pinch-to-zoom when played on small screens. Pinch away!

We just submitted the iPhone version of World of Goo to App Store for approval, expect it to be out soonish! We will post again when we have a final release date, but in the mean time, there are a few things we’d like to share about it.

We realized after the fact that the way we set pricing for the iPad version wasn’t very friendly to fans and early adopters (started at $10, lowered to $5 after a month when we realized $10 was too high).  Having learned some lessons from our first App Store release, we decided to do things in the most transparent and fan-friendly way possible this time around.

The iPhone version of World of Goo will be priced at $2.99 in the US (and the usual equivalents elsewhere).  BUT, it’s going to be discounted to $0.99 for the first 24 hours after release as a way to say thank you to the early adopters.

Additionally, we thought the most fan-friendly thing to do with the iPad (HD) version is to make it universal.  So if you already bought the iPad version, you will essentially be getting the iPhone version for free.  Bon appetit!

One last detail to note about the iPhone version: it will require an iPhone 3GS or iPhone 4 to play.  The iPhone 3G was simply not fast enough to run the game as smoothly as we would have liked it to.  For the techies among you, the requirement is an armv7 or better processor.

[UPDATE: for those of you asking about iPod touch, the game will require a 3rd generation iPod touch or newer]
