It's a great idea! I like the simple gameplay loop of just gunning enemies down and swapping arts depending on the formation/density.
I think it's got potential to be sick with more development.
Super fun game! I enjoyed the puzzles of deciding where to use each phrase a ton, and the checkpoint past the first bit was really appreciated.
The writing was interesting and really made me take a while to think before I clicked past each page too.
Couldn't quite finish one of the alternate completion methods, so I'll come back to this later.
Nice submission!
