The damage and death effects are wonderful. Hope to see more manga panel zoom-in shots.
The movement feels nice, but the digital aim is awkward. I don't know if you're expected to use a controller, but if so, analog aim would help a lot. And I'd recommend an in-game input mapper (I use Rewired in Unity). I used a controller but the keyboard controls were somewhat confusing at first too (the button to read the computer screens is different from the dialogue confirm button).
