Dimensional is a game that takes pretty good advantage of the roomscale concept to provide interesting environmental puzzles. You have a sidekick parter named "Digby". He's a floating robot head that follows you around. You have some control over him, and you can send him towards certain danger, to try to move yourself further through the game. You solve mostly basic environmental puzzles to advance the story. You can tell that the game is an indie game lacking a large team or a large budget. Still, you can admire the ambition of the developer, despite it's indie nature, and it's also only 5 bucks. When you factor in the value part of the equation, it definitely helps it's argument.
