I'm aware of some of the pathing issues, its a separate bug from the enemies fleeing and is a bit more difficult. There should be a fix in the next update though.
The fullscreen screenshot issue I wasn't aware of, I'll look into it and see what I can do.
I also appreciate the suggestions, I'll keep them in mind.
As for the updates, I considered 1.0 complete enough to be released but I always intended to continue developing the game after release. I wanted to gauge peoples interest and get feedback from real players, which has been extremely helpful going forward. I do still consider this on active project, but I wouldn't call it early access or anything like that. You could consider it like a sort of 'soft launch'. While I can't say how long I'll keep updating the game I don't have any plans of stopping development anytime soon. I hope that answers your question.
I'm glad my game could be your first purchase on here. Thanks for all of the feedback and suggestions, I'll be sure to take them into account for the next update.
