I dont know what you mean by "features to keep flow of combat going" all the core features of the fighting system are in place and have been for a long time, I currently don't plan to add much else to the gameplay mechanics, but I will of course keep experimenting with what's already there in the future. I plan to add things like more bosses and enemies.
As for bugs, any time I put out a build and it has bugs, its fixed and re-upped within hours of someone telling me, or sometimes I find it on my own. It doesn't take long at all.
