Hey, I'm sorry you had to encounter a bug that ended your playthrough.
Thanks for putting so much time into trying to improve Kanpeki and giving us feedback, most of the things you've said in your video and in this comment makes sense to me, feels fair and will be changed in the final game. We're currently working on changing the controls to something more similar to PS2 titles such as Fatal Frame for the steam release of the demo. If you have the time, let us know what you think of these controls when the demo gets out!
Loved the video!
