This one was a bit rough around the edges. Though, you're on your way to a start in creepy game making. I was a bit frustrated at first not knowing how to play the game. But, I persevered and figured it out! Though, I'm still a little confused about it. :) Good job finishing a jam game and in Scratch, too! Very nifty!
Some improvements would be to fix the spawning at the beginning, and maybe having the game automatically get into a beginning state. Having textures for the ground graphics will also give the illusion that the player is moving, right now it's hard to tell you're moving in tree free areas. Footstep sound effects would be nice to give the illusion you're moving as well.
By far the best part of the game you did right was the chase sequence and having the enemy popping up. The music changing to something more intense when the enemy is near was pretty well done. Running from the enemy actually felt scary and I felt threatened and spooked out during those sequences.
