Good game! Definitely deserves more reviews. I like the art a lot. It's very tron, and very readable for gameplay purposes. I also liked the approach to the jam theme, and overall how the player is controlled. I liked the bosses too.
As feedback, I would put fences around the first arena. I think it would be more satisfying if you can focus on the boss here, and not in the environment to not fall, but at least you bring the player back with just a bit of hp punishment. And about the player controller, I liked it and it's satisfying but maybe reloading while you are still aiming can reduce the number of inputs and feel more accessible for newcomers?
Anyways, I liked it a lot and it deserves good rates. Hope you get more reviews before the deadline, and if you have some free time, it would be awesome if you could also play our entry!
