While some games like Hacknet and Uplink present relatively realistic focus on manipulating systems and code, many revolve around a more game-y form of programming, from Gunpoint's Crosslink to Spacechem's chemistry veneer. Glitchspace combines first-person puzzle platforming with a sleek visual programming mechanic.
From exploring the game's odd stages to mastering the programming puzzles in both the campaign and Sandbox mode, Glitchspace is easily my favorite in the genre. The interface is simple to use and easy to understand, and there's something quite satisfying about seeing the effects of your manipulation in real-time, as platforms shift and change or launch you through the air. Exploring with the programming possibilities in Sandbox shows the potential depth for challenging and complex puzzles, especially when you find yourself drifting through the world because you made a platform disable the effects of gravity.
Glitchspace was completely revamped in a recent Alpha 2.0 update, improving everything from the art style to level progression and the look of the programming interface, and the game continues to grow on Early Access. The developers are currently working on a better tutorial, a level editor, and crafting new challenges.
