Saiko no Sutoka has a simple premise, but remains challenging with the girl somehow able to keep up with you so closely at times. It definitely works well to provide "I am about to be stabbed" vibes, especially with the audio cues, although I did feel considerably less in danger once I found it wasn't one hit kill. Overall, it's a good foundation for whatever is planned in the future. Hopefully some form of plot will be added so we know why we're there.
Good job, dev.
