I wasn't really sure what to expect coming into this, but gosh this was so gripping. The feeling of entrapment, even before entering the cave, was so good. Got real 'Enigma of Amigara Fault' vibes in just how you could see the end from the moment the story started, but all you can do is watch it unfold. The writing really sold the protagonist's predicament and decisions; even knowing how stupid he was being it was understandable how he came to that point and why he'd felt driven to do something so reckless. Also, I'm not usually affected that much by cave stuff/claustrophobia, but DAMN did this make my skin crawl. Excellent work!
