I got 2020 points.
I really loved the design of "hitting an obstacle is doubly bad because it's one fewer thing to slow down your pursuer." That just works perfectly with the dire theme for your game. And the creepy window figures are a great touch. The ramp up to a game over was a bit drawn out, but those last few moments of crashing into something then seeing the rubble pass by the shadow a moment later was peak horror film "clumsy victim" trope. Excellent. Chef's kiss.
A bit more tuning on the individual run feel and this could easily be a nice little mobile game gem. Well done on making this in just a few days!
