Maybe this isn't really Jeff's work? I checked his website, and there is no mention of an iPhone port. It lists several such as Mac, Windows, DS, GBA, but nothing about iPods. It is kinda hard to believe considering the amount of polish in POWDER and it being ported to pretty much everything.
This is what I am starting to think - that someone just got the nod to port it and this is the result. I do feel awful complaining about it because Powder really is a great game. I recommend Rogue-like-lovers to at least give it a play on another system, if only to forgive this port.
I hope so. Whoever made this port and priced it a ten dollars should be ashamed, Jeff Lait or otherwise.
