Evaluation
Retro/Grade launched on March 20, 2013 as a self-published indie title by 24 Caret Games. The store description presents a complete, self-contained product: 10 worlds, a full campaign with 6 difficulty levels, 130 challenges, over 50 minutes of original music, and dozens of unlockable ships. There is no DLC listed, no post-launch content updates on record, no developer roadmap or announcements of future content, and no indication of any ongoing development activity. The game shipped as a finished product and has remained unchanged since its release. There is nothing to suggest additional content was ever planned or delivered after launch.
