This one is really good! The controls were hard to get at the beginning, but once I got the it turned really satisfactory. The boss is extremely creative, I love the animations and the algorithm it follows. I really appreciate the twist you gave to the clasic space shooter.
My first complain comes with the boss. There's a blind point of its attacks in the back of the big bars. With that trick it turns really easy. My second complain is that I think the algorithm of the asteroids could be improved, they can become a little unpredictable. That's not an actual issue as the game can be completed, but a better balance can be reached.
You made a great job with a clever approach to the jam's theme, very vell done!
