Beautiful and powerful entry!
The presentation is a treat to the eyes, the writing is superb, and the connection to the theme is really good! I specially liked the intentional controls on the Ice Cli--- Uhh, I mean, Snow Mountain Climbers section of the game, it really nailed that clunky-but-fun era of games which I profundly adore.
Writing-wise is great, it keeps you invested enough to keep playing and keep asking questions about Henry himself, wanting to hear more about his dreams and their meanings, and how will he woke up from this nightmare, till... well, you know.
Not wanting to be dramatic, but the last I can say is, based both on the introduction and the beautiful message of the credits, if you feel like you need help please ask anyone, really. No one is truly alone in this world. I wish you the best!
Really amazing entry, definitely one of my favourites! Great work! Please, keep it up. ^^
