Thanks a lot for your comment.
I'm glad you like my game!
For the cat icon, that's a Niancat—it's a pretty rare special ability. When it hits an enemy, it destroys him and then bounces off another enemy, it can do this three times in total. It's very powerful and quite rare. The bullet's skin is pretty funny. I recommend you try to find it again! :D
That’s bad about the Itch connection. What message are you seeing? Is it an error, or do you just not want to log in?
