Hey, thanks for playing and recording a video, I appreciate it a lot!
Really impressed to see you blaze through the whole demo in one sitting, some people had a lot of trouble previously finishing the second and third mission. Your feedback on the settings, UI, text, and controls is all valid and I'll be updating them soon. The mission and main menu screen is eventually going to be redone from scratch; right now I'm just focusing on getting gameplay done which I think is the most important part.
Thank goodness you didn't go for an S score by the way; you were right to not trust the end screen since the A+ score is always shown. I haven't decided yet what a good score should represent, but I suppose it really should just be a mix of good time + least amount of hits taken.
