Not a problem. Happy to clarify.
Okay, look here at what you wrote. You answered the question for me so, thank you kindly.
1st Paragraph
"If game devs aren't willing to pay, why they would pay you if you just play games?"
2nd paragraph
"but every game dev sees value on playtesting"
Haha that's why.
Re: Testimonials - "You mentioned your testimonials, but let's be honest, people will always call you an angel if you help them, even more considering you said that you just play games, while they are saying you really boosted their game."
Not true. You can't force people to do anything they don't want to do. Even if you ask or beg.
I'm not sure what your goal is as a game developer. If you're hobbyist, the service may not be for you. If you are hobbyist wanting to transition to be professional then, that's good. I looked at your catalog of games, but do not see any comments on any. Not that it means anything negative, it's just interesting.
