A simple idea, cleanly executed. Well done!
A coupe of points for improvement -
I died almost immediately, before i had a chance to figure out what was happening - consider starting the player away from the enemy so that they can make visual contact and know how long they have to take in their surroundings before needing to act.
Something in the UI to keep track of how many times the player has won / lost would be good.
Personally i found the skewed camera angle a little off-putting.
Thanks for working hard and submitting to the Jam!
