The mood was really great, and the background sounds added nicely to it. The old film effect was cool too! The rat felt responsive, but I had a hard time getting past level 2. with all the spikes, and the time needed to accelerate the rat to "full speed" in order to make the jump. But I'm not a platformer, so this might be perfect difficulty for others. Anyway, I had fun playing it, and I hope you had fun making it!
