I highly doubt it, no other game on the iPhone is even over $10, I would probably go out of my way to avoid it if it was 15 or 20
The game is going to be 4.99$.You should go to the site Moldy Tomato recommended.You will find all the details there.
Ah, I see, I thought v-dog meant that the iPhone one was 15, when he was saying that the difference between them is 15 and so what's so great about the PC version that's worth paying extra for. OOoooookay...... well I would guess that the level editor would be one thing, I reckon you'll be able to download custom levels from the playground onto the phone version, but you probably won't get the editor itself, would be one thing, plus I doubt it'll have as many levels in it as the PC version.
EDIT: Just watched the video, well if it's got the level editor then I'm not too sure apart from there wouldn't be as many levels, but I guess we'd have to ask Petri about why, then.
