EDIT: THE GAME IS BACK!
So for some reason the game no longer shows up on the game page, but I was actually able to play it before it disappeared, and so this is what I remember of the game play: It was a sidescrolling platformer where you run to the right and can use WASD to navigate the obstacles, which took the form of platforms and pumpkins. A ghost on your left would continually chase you and if you let it touch you, you lost the game. You could also throw candles as projectiles.
I thought it was a really cute idea for a game and the art/sprite work was really very good - it was super atmospheric and was a very cohesive Halloweeny look, especially the parallax background. The ghost was set to just the right speed that it provided tension and made you always feel pressured to keep walking, but without being frustratingly easy to get caught by. I wasn't ever able to figure out how to score, but that's okay, since I just played it like a better version of that Google Chrome offline dinosaur game anyway.
I hope the game gets reinstated on the page at some point! More people deserve to play it!
