Really great game; the minimalist aesthetic is a delight and the humorous meta writing iss a real joy to read.
It's a really polished piece, and honestly there's not much constructive criticism to give as I feel you pretty much achieved exactly what you were going for!
That said, I wasn't hugely aware of what my score was being determined by... like I was releasing the keys to gain core but i was also destroying them? At first I thought I wasn't meant to destroy them haha.
But really, the polish is so so strong, and I love the overall concept, definitely one of my favourites from the jam!
