Developer Testimonials
What indie developers say about working with me.
These testimonials reflect the detail, honesty, communication, and practical support I bring to every D Rock Games project. The work has included qualitative playtesting, Steam page feedback, launch preparation, and broader guidance around how a game is presented to players.
Every project is personally handled by me, Derek Larson. You speak directly with the person doing the work, and I stay available after delivery when you need clarification or want to discuss the next step.
What Clients Consistently Value
The same qualities matter across every service.
Whether I am testing a build, reviewing a Steam page, helping prepare for release, or shaping how the game is presented, these are the things developers mention most often.
I do not invent problems to make the work look longer. I explain what needs attention and what is already working.
I take time to understand the experience, its strengths, and what the developer is trying to accomplish.
Communication is direct, timely, and collaborative from the first message through follow-up.
Featured Developer Feedback
Clear work, practical guidance, and genuine care for the game.
“Derek gave the Scales of Silence demo a careful, detailed pass and delivered one of the most useful reports I've gotten. He told me up front the build was already in great shape, then found genuinely helpful things anyway, no filler and no padding to look busy. As a solo dev, that kind of honest, specific feedback is exactly what I want. His playthrough notes are thorough and easy to act on, and I could put his suggestions to work right away. Fast, honest, and clearly invested in the games he tests. I recommend him without hesitation and would happily work with him again.”
“We can’t thank Derek from D Rock Games enough! Derek’s timely and thoughtful notes were instrumental in polishing our demo and improving some weaker aspects. His notes were specific, comprehensive, and most importantly, actionable. Derek not only stress-tested for practical issues and suggested clever solutions, but also conveyed real interest in our game’s world. We are so grateful for Derek’s helpful feedback!”
“Derek’s thorough testing and well-formatted feedback helped us prioritize key parts of our game. One of the most important, and often overlooked, areas was support for streamers and content creators. Derek doesn’t just test a game for functionality; he also looks at its marketability. For indie developers, that perspective is incredibly valuable, because marketing is everything.”
