I'm incredibly impressed this was done in three days. It's a game I'd be glad to buy with a bit more polish (like saving) and content. Oh hell, considering the trash on Steam I'd be glad to buy it as it currently is. The art is absolutely gorgeous, and I'm not just talking about the two beautiful women. ;) The music suits the game very well and feels relaxing. Kinda weird to have relaxing background music while being buried alive. The sound effects were good, and I just loved the squeak the rats make when you click them!
Speaking of the rats, I've mostly ignored them during the conversations/card games and didn't experience any penalties. If there is a penalty for taking too many rat bites, it takes a while to incur it. I saw on the itch page there were different plans for the card game, but they weren't implemented before the jam deadline. Was the card game going to be a gauge on how well Remie favors you? Early in the game you two don't match often, but as the game progresses you match more often if you're on track for her ending. If so, that would've been cool. If not, what was the plan for the card game?
I don't see anyone else mentioning this, so I guess either incredibly obvious or I'm way off track: I see this as an allegory for a relationship on the rocks. Karina being convinced you're dead is her giving up on it, and the burial is her deciding how to end things. Remie is someone you're having an emotional affair with, with the card game representing spending quality time with her and (if I'm correct about the original function of the card game) connecting with her in a way you can't with Karina. And the rats represent, uh, I don't know. Work/responsibilities? Okay, my interpretation might be falling apart here. But I feel like this game is you deciding whether to save your failing relationship or to just start a new one.
This is easily my favorite game I've played so far this Ludum Dare. I'm definitely following on itch. And I'm not even into visual novels.
