Had A Good time playing, I found the atomsphere to be very chilling I was pretty scared to walk forward at times terrified that something was gonna pop out. The tunnel scene was really creative and a great use of the lighting.
some cons were that although the atmosphere was tense I never really got to see to see the creature until the end. would have loved more visual scares or quick glimpses of the creature. and it could definitely use some soft atmospheric background music felt really quite at times.
overal for a first game I think you have done a wonderful job and look forward to more of your work
