The idea is that it's a top down shooter but without a gun. Instead you reflect enemy's shots back at them with your lightsaber. You can also kill them by hitting them with the sword which feels like an inclusion not really in the spirit of the jam. Unfortunately there's not much else there. There's not much feedback on the reflecting of the shots so it doesn't feel very satisfying. And there's nothing else you can do in the game other than kill the same enemies in the same room.
It's also unfortunate that the game is easily cheesed by just turtling in the corner. On the whole I didn't find this that creative or that engaging. Sorry.
