Cool! This is very simple, and because of that, fun and you can grasp the game instantly, which is super important (especially in a game jam). Strategically it's interesting too, because it seems like you can keep the gloves matched to the enemy's and sort of "push them around" and make an opening for yourself.
I'd love to see more levels of this & expanding on the idea. I think a little random sideways movement from the enemy would be a good gradual difficulty increase. Also, the scale of the players could have cool consequences like making them slower but more powerful, etc...
Neat little game :).
