Hello! I really like the concept of the game, and the art of the characters. I enjoyed the "banter" of the character dialogue on the tutorials too.
On my first try, I was following the tutorial, but then my first mission failed, and I got stuck, as other comments have also mentioned here. There are a couple of mistypes on the dialogue, so you might want to run those over some program to fix them out. Even Word spell correction would do.
Found a visual bug on the tutorial where the character portraits appears over the button:
After I got my second mission, I tought I had soft locked myself again. But ended up figuring I had to create a new prove? It got me really confused. I think the game wants me to build multiple proves, with new technology as it gest researched? That should be better informed to the player somehow. And perhaps we should have a visual indicator that we already have some proves on space?
At this point, I got new missions, but just simply could not get to do them. I tried creating new proves, but there was just no way to progress, and no further researched to do, so I just gave up.
I think you have an interesting game here, but needs a lot of work on testing, to make sure players can properly learn how to play, as this concept seems quite novel.
I'll look forward to see how it develops!
