We apologise for the late feedback:
This is the most literal interpretation of the theme I have seen yet: literal anthropomorphized weapons. What a neat idea for the jam! I really like the art theme as well as the choice to use pixel art for a visual novel. It felt like it took a bit too long to get to the first dialog choice, but the story is absolutely interesting. I would suggest that, when you fully implement the choice system, that the option to make a choice happens sooner in the story. I'm not sure if it was intended, but the occassional glitching of the characters during certain lines was an interesting addition to the feeling of the lines at that point. The music is a little disjointed in theme, but it is understandably hard to find cohesive music for free use online that suits the theme you are going for. Unfortunately your master volume slider does not affect the music volume, and the song with the strings lacks audio balance compared to the other somgs (it is louder).
Aaaaa you left edit access on your GDD! You should lock it down to prevent people from messing with it. I like the way your GDD is laid out, and the great amount of detail you go into for each section. Listing the roles and info for each person on your team is something I love to see. More examples of how you intended to handle the UI and choices would be nice (even if just using a Ren'Py standard layout) along with a list of the art software used. Otherwise, very nicely done.
Thanks for entering the game jam, and I hope you all continue development on this game and publish it because it is really interesting! Look forward to seeing where this goes!
