I must admit to have neglected the fact that people might not have much desk space space to move the mouse on or using a touchpad
so the game might very well be impossible to beat under those circumstances.
Try to increase you mouse sensitivity in your pc settings if possible.
And yes if the direction changes and you hear a drip noise it means you where too slow with the mouse, you have to move it in the direction the arrow points.
I'll see if i can figure out a solution to the mouse space problem (i think using wasd and the arrow keys at the same time should present a similar challenge), but i'm gonna be busy for the foreseeable future so i can't tell when i get time to update the game.
