Thanks for playing. That was the exact intention behind the props so I'm glad it worked out.
After the corn maze you are meant to go back inside the house. There were a few more doors there. We wanted to inform the player somehow about where the key leads to but ran out of time. A quality of life improvement to come.
Was the first health pack at the car right when you start or inside the house? Very odd, I never seen the packs not work. The prompt will tell you if your health is full so maybe you werent hurt?
