What a thoughtful and affecting game bound by a very original concept. I interpret the game as exploring the very morbid reality of attachment and death - one partner tends to leave the other after life, but this game explores a fun idea. What if you could take your partner with you to the grave, quite literally? The narrative does an excellent job in shouldering the creepy and sentimental implications of this quite well. As a short game with minor dialogue and some basic point-and-click mechanics, what really shines here is how a brief game with a greatly original idea can sort of be bigger than the sum of its parts.
The attention to detail is great here. The context dialog changes to reflect the protagonist's predicament. The visual presentation uses its minimal motifs incredibly well, with the pamphlet showing how much thought can go behind simple little acts of worldbuilding. Seeing that you created the excellent Any Port In A Storm for a previous jam and were also influenced by Who's Lila? helped make a lot of things click - you have a good knack for uncanny surrealism and morbidity in your approach to games, and I really like it. I hope you're able to continue creating experiences like these as they're very memorable to play.
As far as constructive feedback, there's not a lot, but maybe with a little more time aspects of the UI could have been cleaned up - can be a little tricky to click the right spot to activate the hole, or add slightly more in terms of visual details. But for a jam game this is about as good as it gets. Incredible stuff.
