You are right, sfx and vfx are not my forte and I've been focusing more on features than presentation but hopefully that will change.
Funnily enough I had cirno turn into the direction she was walking in but I was told to make her look at the pointer instead, I agree it looks weird and I might try to take a hybrid approach in which the legs and the torso turn independently: legs pointed in the direction of movement, torso pointed towards the louse.
Visibile weapon similar to enter the gungeon has also been planned for a while but I've been postponing it, now might be the time, I do need to make presentation better now that my core gameplay is in place
