Before anything else, I very deeply appreciate your time taken analysing the noticeable faults that we could not fix on time.
I very much agree with your points, where the gameplay was lacking, and the dialogue sequences (which we've received many critiques about), which was really just the way they worked by default.
I may reassure you, we are currently using most of the critiques to overhaul the areas that were lacking. The combat system is being completely reworked, from scratch. More sound effects, music, and portraits are being done for a more polished demo, after which we will move on to complete a post-demo version in the long term.
Hopefully, you may still be interested then to experience it again.
