Vita bump. Figured I'd post initial impressions.
After having my 360 save trashed in the middle of Episode 5, I bought the retail copy that contains Season 1 and 400 Days (don't worry, I haven't touched the latter so no spoilers).
After completing Episode 1: Chapter 1, my verdict is that it's a pretty rough port job from Tell Tale. The animations somehow come off much uglier in this version, and everything has a noticeable downgrade in the visual department outside of Lee. Effects are also spotty, with blood color being changed to grey instead of red (again, too early to tell if this is a consistent issue).
The major issue here is the transitions. While the loading times are comparable, and possibly faster, than the console versions, scene transitions and dialogue switch-overs are extremely choppy.
The game offers you two choices to play: traditional controls and touch controls. You can not mix and match these styles, which is disappointing as some scenes would arguably make sense with the touch options, and dialogue choices are far easier to read in the touch set up. However, it's generally better to control Lee through traditional controls.
The game also offers multiple saves (takes 12 MB of memory card space in the retail edition) as in the other versions. It's too early to tell yet if this version is prone to the save eating bug that plagues the other versions on consoles.
I will update this when I get further in the game and can pass proper judgement on all the details and issues in the Vita version, though I may save the majority of it for an upcoming excursion in September.
