Developer Testimonials

Feedback from indie developers I’ve worked with.

These testimonials come from developers who received D Rock Games playtesting and QA reports. Each report was personally handled by me, Derek Larson.

My goal is simple: give developers clear, honest, practical feedback they can use to improve their game before launch, festivals, Steam traffic, or public demos.

“Derek provided structured and well-organized feedback by breaking down his review into clear categories. This made it easy to understand which areas needed improvement and why they were important. His ability to quickly identify weaknesses was particularly valuable, as it allowed me to address issues efficiently and make improvements in a timely manner.

What I appreciated most was the clarity and specificity of his feedback. Rather than giving general comments, he clearly explained the strengths and weaknesses of each aspect of the game, making the review process more productive and actionable.”

Town of Tinysville capsule art
“Derek from D Rock Games sent us an incredibly detailed report for our game demo. His scoring wrap-up was incredibly helpful to diagnose the strongest and weakest aspects of the game. His two biggest suggestions were updating the font for better clarity, and uploading a new batch of screenshots for better color variety on the Steam page. Both suggestions were incorporated into the game and have significantly helped.

His detailed playthrough notes were probably the best part of the report. Because of how the notes were taken, I was able to see step-by-step his thought process.

Overall, Derek's report was very helpful and his feedback aligned with the structure of the game.”
