Post what round you got to!

Master gravity and own space. Its you, your black hole, and your gross alien-spawn against an infinite onslaught of enemies.

Asterism is our exploration of a unique mechanic in the Bullet-Hell Genre. Use a blackhole, master gravity, and adapt to a fast-paced, close-range arena in our entry for the 2022 Bullethell Gamejam. 

Planned Changes:
(Thank you to everyone who gave feedback) 
Add a better background. It is confusing to move around. 
Adjust or remove self-damage. 
Tune the blackhole.
Add finer movement. Allow micro-dodges.
