Thoroughly immersing from start to finish. Having the hair swish tied to mouse movement is such a great gamefeel interaction, and it's incredible how after a moment you really acclimate to navigating with Sera's echolocation. Really like how much atmosphere is in this game, gradually pitching from pleasant adventure to an unknown terror.
The use of different colours for things makes reading the echolocation feedback easy and intuitive, which made the more tense sections really fun as you're trying to get away from danger while also trying to figure out where to go. Genuine relief when I finished, that was a perfectly executed Squeeze and Release. Sakurai would be proud!
