Multiple things bugged me out, but I don't know if it's by design or if it's buggy:
- the camera aim not aligning with the mouse
- ghosts attacking me repeatedly while my camera was on cooldown
- ghosts walking over my head?
I also think it lacks a bit of sound ambiance.
Other than that, the level design is cool even quite a maze (maybe that's meant to be) and most things works pretty well! The animations are neat; aiming aside, the camera thing work pretty well; the bits of story all around the school are cool too!
