Boxes is a very solid Room-like game with a decent number of short, self-contained puzzles and a fairly vague overarching plot. I think some of the visual effects could use a 2nd pass and the ending is rather abrupt with none of the payoff that I was hoping for.

Otherwise I think that Boxes is decently balanced. There's a steady skill curve (although the game is never difficult) and the hint system simply shows you where to look and lets you get along with playing the game. A bunch of different cultural themes and time periods are explored in the game's style with none of it looking too out-of-place.
