Ayo thank you for trying our game on your stream, just played you game today!
I think that as your first game jam, this is great and I really like the concept! I think that it is okay to rely on physics to make a game but I feel that the player should still have a little more control, for example: atleast have the knife and mouse be on the same position all the time (not having the knife move to the mouse position) so that the player can have more fun interacting with the physics instead of having to fight it.
