Honestly pretty cool, reminds me of these Game-n-Watch type games!

Though I have things to say about the gameplay:
* Knowing when Seija can shoot would be good. Nowhere is it indicated she has 2 shots on cooldown.
* The Two-Lane Reflection ability is kinda confusing too. As reminder:
- Shift Z = Middle + Bottom
- Shift X = Middle + Top
- Shift C = Top + Bottom
This mapping and wording made very little sense to me at first.. It's just not quite intuitive to me (though I'd like to hear what other players say about it).
Why not put it this way: Shift reflects where the non-Shift version doesn't reflect? Like:
- Shift Z = All but Top
- Shift X = All but Middle
- Shift C = All but Bottom

Once I got somewhat used to the gameplay, the game seems a bit easy? Heh. That's fine I guess, the core concept is awesome. Doing reflections back to back without missing any needle feels so good!
Just make sure that Seija's shots do not blend in as much with the background. Even if it doesn't affect the gameplay, it'd be nice to see that your own shots hasn't vanished into thin air.

"Added emotions during dialogues." is one of the funniest changelog lines.

Would've liked if there was more of a pattern to Shinmy's movements, rather than it being seemingly random. The shot also seems to have a system that limits how much you can shoot. What determines it i dont know. Is it time or just after every reflect?

Atleast the reflect window is pretty intuitive and forgiving. You just reflect bullets as it hits Seija's hands.
