Thanks for your feedback.
Actually I have asked the same question some time ago via: Your Browser does not support WebGL - #6 by hyperknot
Totally forgot. I went through the instructions and via the chrome flag, I got it to work.
Regarding the pricing. Don’t get me wrong. I totally understand you have your cost, and you very much deserve to actually gain something from this project, not only get break even.
I will check with my BVB Fanclub, if I can relay the costs to it. Maybe I can work something out.
