I had a huge smile on my face when I completed this. It's short obviously but the atmosphere truly was great and the lighting was gorgeous.
A lot of horror games that try to stress you just put you in some kind of maze where you're supposed to collect something and avoid a monster. It's rare that you're actually forced to do a specific task under pressure and I enjoyed it a lot. It was very refreshing and I would hope to see more games do something like this.
All in all, good proof of concept. I had a lot of fun so thanks for making it. :]
