Hello, I agree on most of the review and here's my thoughts on that.
Yes, the story is pretty average and there will not be much added to it except the endings. And they are coming back from Annie's date.
Soundtracks are made by xDeviruchi and it's not specifically for this game but does fit well.
Zoom feature was added when your exact location was not visible on map. By zooming out you could understand the design and know your location on map. About the crouch system. There are two methods that can be used. Basic and Advance. Basic has the setting you were talking about.
The game was made when I had quite less coding and game design knowledge so it's lacking in combat and enemy AI. Because of that even Annie's gameplay is not that different because it has to complement enemies from Hailey's game.
If it's development began 6 months ago it would have been much better game.
