I removed the unspiraling effect as I thought it took away from the interaction.
I added some noise and contrast adjustment to mimic horror aspect of the manga a bit more.
I added a sort of another phase warp which has acceleration component to it and kicks in after 200 frames to mimic spiral behavior from the anime.
+ some other changes with canvas and general codebase.
