Thank you for the detailed feedback. Since you scored over 150, I’d say you’ve fully experienced the game.
I also noticed the lack of background music more clearly after uploading it. I did try adding some tracks, but I realized the music changed the game's impression too much. I felt I needed to define the game's identity first to choose the right music, but since I couldn't do that clearly, I decided to remove it for now.
Your suggestions for variation are interesting. Adding things like bombs with double wires could be a good idea. Thank you for enjoying my first game despite its shortcomings.
