That was a very interesting experience! I'd say that an Adult warning is warranted due to the narrative.
The pictures, effects, and sounds really does bring in the atmosphere vividly. However, I would love to see this be fleshed out more especially in terms of the whole UI design and text font.
Since this is your first time doing a project like this, this is really cool. There is so much potential in how you can develop just from this. Thanks for submitting!
