Cute game, I enjoyed sneaking around and trying to distract the guards but I found it to be a tad too unforgiving.
I think the game needs a sound effect for the cat moving, and when the cat collects a fish it should be a chomp or something.
Also the camera moving with the cat is pretty jarring, I suggest making it stay in place and only moving it when the cat goes out of bounds.
Also consider changing the colour of the green line, right now it blends in with the yellow ones on the floor.
Anyways, great game for a first game jam!
