Thank you kartezjusz2009, for taking the time to test again.
Yes it is possible to set your nickname: By clicking on the pen icon left of the textbox where you can enter chat messages. When you click on the pen icon, a new input box appears in which you can enter your nickname.
Now that you mention it, I think this needs to be more obvious. I added a backlog item to add a tooltip to this button to clarify its function.
Thank you for drawing attention to the broken player profile links. I added fixing this to the plan for the next iteration.
I am currently working on migrating the lobby, online games, leaderboard and player profiles to a new platform. Because of this infrastructure change, I have to finish some other tasks before I get to fix these issues, but I guess the new update with those fixes will be available in December. I will make sure to post a new devlog entry here on itch.io then.
So my question is: is there anyone playing the game? Or maybe I can find you, distilledgames, there one day? :)
Sure, I would be happy to meet for a match. When do you have time? If I see correctly, you posted between 12 and 15 UTC in your last posts. I am usually at work this time of the day from MO-FR but I could come online this time on a weekend.
