The PC indie puzzle platformer, Thomas Was Alone, has received much praise since its release last July. The game is now being ported to the PlayStation Vita and PlayStation 3, so players can solve the multi-character, 2D puzzles on the go. We checked it out at the Game Developers Conference in San Francisco and the simple little downloadable surprised us.

The game starts out simple, teaching players how to move a single little box around a stark environment. Eventually more rectangles are added, each of varying heights and jumping abilities. Players swap between the three Lost Vikings-style in order to solve environmental puzzles. Sometimes you’ll have to use one box character as a stepping stool for the other, or as a bridge to cross a gap. The platforming feels fluid and each box’s differing abilities are readily apparent. While the game starts out simple, the complexity of the bite-sized levels evolves into anti-gravity brain-teasers and VVVVVV-esque falling sequences.

Thomas Was Alone also stands out thanks to its inventive narrative. An English-accented gentleman adds color to the goings on by describing the nondescript boxes’ personalities. A simple line about two plain-looking boxes resenting one another adds a surprising layer of personality to the visually sterile game.

The game, originally developed by Mike Bithell, will be available digitally on the Vita and PS3 April 30.
