Hey Kaish!
You made a really fun game for the game jam. Unfortunately the version before deadline seems broken, but the post jam version shows what you were planning. With that in mind, i would add some ui elements to the post jam version so i could see number of kills, what kind of level i was at and maybe make something more out of the really neat sigils you made for the bosses. Maybe you have to collect the 4 sigils to free the people. Have a levels map in between where you move towards the boss and once a boss map is completed you see the collection of sigils becomes more and more complete.
Awesome work! Better luck getting it all within 48 hours next time!
If you have time I would love it if you could try my game and give feed back. Its called Drone.
