After reading the comments and tried several times I started to understand the game a little. Great idea it feels very original! I think maybe you can mark the slime and banana somehow(like change color or add a frame) when it is seen by the inspector to help the player understand what the score gets minus from. And maybe make it into small levels to let player practice(since the mechanic need some time to understand), but due to the time limit of the jam, I think this is really a good game!
