I like the storytelling! The idea of having to survive a random amount of time with random ressources is cool too, but of course I guess it suffered a bit from the lack of time (this is a gamejam after all)
What bothered me the most was the lack of feedback on the enemies (I don't think I managed to kill those armored guys a single time) and of course they go to the same speed as the player so when they caught up to you it's game over.
Overall good job! I loved the music choice, combined with the visuals it really set the mood.
