Oh man, I love this game; my ending gallery is 100% complete. x) I lost -a lot- of sleep playing it with my younger sister, who demanded that I translate everything to our native language since she can't understand English, haha.
If I had to describe HL in one sentence, it'd be 'more than meets the eye' without a shadow of a doubt. :V Certain parts honestly made me cry - not only inside, I mean 'cry' in the literal, 'tears rolling down my face' sense (and it was not caused by sappy romance). Nageki.... BBL.... (sniff) Without spoiling too much, if you're a fan of weird plot twists and dystopian settings, this lovely dating sim should tickle your fancy. 10/10, would recommend.
Ah, so there is another fan on here! Hello!
You're totally right about it being more than meets the eye! Most people are just "Hahaha, birds are funny" until they actually play the game. And, ah, yes, Nageki; he's my favorite. ;w;
