"Constellation saved!" there is one star left and it's fading away.
Jokes aside, that was interesting! Surprisingly grim, but competent, complete, and atmospheric.
The stun mechanic was very confusing at first; I thought, by spamming the blade button, I was accidentally activating some weird melee combo move that was also bad and slow. Realizing that it was from being hit made me feel better, especially since the area of effect attack offsets the stun and prevents a degree of stunlock!
All-in-all, great work!
