Fun little game, I like shmup games so I’m biased.
I liked the space theme but I don’t see much of the build to scale theme outside you are saving energy to destroy the white hole. The ending is funny and I liked the visuals of the game. And a bit sad this game doesn't have a bgm.
As for the gameplay, it’s ok, since it’s short, I don’t have much to say and I had fun in these few minutes of gameplay. :)
