Looks like an alright adaptation. You can see all the changes games have to go through when being ported to a mobile platform.
inb4 "I just want 1.2" - The Terraria ports aren't being done by the original team, but they will likely get 1.2 later.
1.2 has that mechanic as well, treating one-block inclines as a slope of sorts.Interesting that they fixed 1 square height jumping. I like Starbound's approach to the problem - you just run and you automatically climb up 1 square steps. There's no jumping involved.
I don't get why iOS is getting it quicker. The Android market is wider for gamers, and developing for Android is cheaper. The Dev kits are free and I believe it's $20 to get an app on the market. It costs something like $100 dollars for the iOS SDK.
