The GUI reminds me some of the 90s webpage styles. Unless it is made on purpose, please reconsider changing it to something up-to-date. You can also make it mobile friendly.
Telling the compelling and vivid story is a very difficult task. Every sentence must be polished in Polish (I hope You see what I did there); strong, simple and thought-through sentences (like Hemingway's) work best. No repetitions, no internal inconsitency.
For example - if you suffer from memory loss - how can You tell the clothing isn't Yours? Or how can You tell how did You get into the cave? Why through barred opening, 20 meters above the ground and NOT by corridor visible to the north?
I'm not trying to discourage You in any way, I'm just pointing things that can be improved.
Cheers.
