Wow, this story and voice acting is ways "too good" for a game jam, lol.
I think i can just repeat what others already told, everything fits very well together and is a real masterpiece, which i would not have expected within one week. Awesome entry.
I also like, that you gave the option to choose moving to mouse or direction (direction was pretty difficult for me, but as soon as changing to mouse it was really fun).
Just maybe a little tip for balancing: As soon as i knew about the possibility of explosions, it was pretty easy. They are maybe a bit too overpowered...
