It plays well and looks good too. Can be very addicting! Good job!
Is it procedurally generated or did you place all those lines manually, then sticking them together by code?
One idea I have is an audio feedback for when the blood stops flowing if your mouse is too far away, and another for when it starts again or the speed of flow is based on the distance to your cursor so it doesn't stop so abruptly
I'd recommended adding volume controls though, the music was bit too loud.
