Nice story and the vibe is clearly for the spooky season!
Unfortunately controlling the character is super hard.
-
First - it is a good practice to rotate character skin to the direction of movement, without that movement is confusing.
-
Second - the camera is clipping with other bodies in the scene. Consider using spring-arm, it allows to avoid such issues.
-
Third - slippery feet can be a fun mechanic, but not right at the start of the game, I believe it should be occasional complication instead of constant obstruction on have to fight right from the first seconds of the gameplay.
Cheers!
