Of course it's an Unreal Engine game - it looks fantastic! I loved the environment So automatically top marks on the aesthetics, its the best looking game I've played so far this jam. The perspective you've created from the vantage point of the rat is so good and feels very realistic/professional. The rocking of the train felt like it might be slightly too much and could be reduced slightly. The cats totally caught me by surprise the first time I bumped into them. Overall this is great with lots of potential if you want to build it out into a full game. Great work!
