Thanks for the feedback! Really appriciate it, as we are wondering if this is something worth going on with. We are from Germany and feedback on new ideas and concepts is not really our strength there, so here is much more fruitful.
As you already found out, the shirts are available already, we launched together with spreadshirt. This shop is Europe based (ships worldwide, but takes a while and some shipping costs).
We have some more ideas in our heads and hopefully bringt them to paper soon. Then we have to see how well this works.
@deniska: maybe invest some more 2 minutes, this looks like a bad copy (literally)
