Umbra Galaxy

Umbra Galaxy is a twin-stick free-roaming space shooter inspired by xKobo. Steer your spaceship around the levels and take out the enemy structures by shooting the turrets. The turrets are connected with power lines that function as walls, and a line will be destroyed once one of its connected turrets is destroyed. Destroying all turrets in a structure will destroy the structure. Once all the structures in a level are destroyed a portal to the next level will open.

Every few levels instead take the form of a boss battle. Abilities can be temporarily enhanced by grabbing power-ups that are sometimes left behind when a structure is destroyed.
