After the boss was "detained" I stayed until the music was over. And I was surprised to see that it ends.
The bossfight was fun, I feel like the falling projectiles attack would be more interesting if they fell a bit slower but were more numerous. The feel of the shooting was great (art and sound fx overall work really well), the feel of moving around, not as much, I'm not used to such low gravity and these platforms have a tricky hitbox compared to their appearance.
