Blockheads is excellent, especially now that they patched it so that crafting/activity timers keep running in the background and your guy auto-explores when he's done. unk Jack's controls and UI pissed me off a lot and love Blockhead's controls way better for a 2D game on iOS. You can queue actions with one tap instead of having to sit there and pick away with your finger at every individual block.
Another good Minecraft game with probably the best controls out there right now is Block Fortress, and you get a nice Tower Defense/Resource Gathering/Base Building mode (which is actually the main mode) on top of it. But if you want, Block Fortress can be 100% played in Sandbox Mode, where it's essentially like Minecraft from my understanding. I haven't played Eden, so I don't know.
Just wish Block Fortress had iCloud support. I don't understand why it doesn't, as both of Foursaken's previous hit games (NY Zombies 2, Heroes & Castles) had it. Also Super Stickman Golf 2 has it, which I'm grateful for. The only thing that doesn't transfer is your dollar balance (or green bucks, or whatever they're calling it), which I'm okay with I guess, since you can just buy the hats on either device and they'll be synced.
