The first thing I noticed was the handling of the text. It doesn't seem to be positioned properly in relation to the text box (left and right spaces are too narrow). Also, there seems to be a problem with the font rendering.
This may seem like a small issue, but it can negatively affect the first impression, resulting in other elements feeling a bit unrefined.
I felt that the feedback when I picked up the battery was a little inadequate. There were times when I didn't realize that I had picked up a battery. However, if you make it too exaggerated, it might ruin the atmosphere of this game, so you have to think of an appropriate expression. That will be a difficult task.
If you want to represent a city at night, it would be a good idea to change the color tones of the bushes and other textures to match the nighttime atmosphere.
I think it is far more important and valuable to strike a chord with the players than to be sophisticated or not. For me, this game was worth it. Refining a game is important, but this is the kind of game I want.
