I'm surprised at this. The version I played had English.
Every version from January 2015 on has had support for English. I guess the speaker downloaded version 1.0 in December 2014, which was in German only. He just doesn't seem to know that there were (translated) updates later on.
Irrespective of that, I was really glad that he included my game in his presentation. It was a very nice overview of Amiga games published in the last 12 months.
