This is really solid! Love the visual style and colour scheme. The time stop + knives system is very flexible as well, it’s a really interesting platforming mechanic - but also narratively feels extremely cool to be balancing on a knife.
I think it would have been nice to interact with the fireflies in even the smallest way - such as the lights avoiding the player when the player moves, or a button-press near them to add them to a ‘jar score’ in the corner. But I’ll admit coming across fireflies in a scene was always a joy regardless of interactivity, so I can’t really complain!
