Not abandoned. It has the same version as Steam and Itch. There hasn't been update on all these stores since 2022 because I've been working on the 1.0 which is coming out in July this year.
Ah, that sounds frustrating. In the live version there's no real way to limit that. I have been working on improving the uniforms system/UI, so I'll keep this scenario in mind.
You might be able to override the warrior uniform for the captured entities by manually adding the prisoners into a control group and then assigning a high priority uniform to that. But, that's just a guess. Not sure that'll work 100%.
