Thank you for playing!
It's kind of funny, I was worried that Type-B would be too good. It is intentional that it's very easy to clear the game with, but I was worried that it would be too good to score with too, so I'm glad that wasn't the impression. My main scoring benchmark is that both shots should be able to get 500 million on Normal, so as long as they can do that, I'm mostly satisfied.
Regarding the time slow - did you know that Danmakufu ph3 doesn't have a native time-slow function, but Danmakufu 0.12m does? I just learned about that recently. What a strange engine.
