Pretty unique game, simple and fun. However still need to polish it more. It will be better with more sound effect in the game. The most important thing is the human sound (maybe footstep). Looking by how terrible the human in this game for rat, it is better if you give us (the rat) a sign about the location of the human by giving a footstep. With a footstep, the player can know whether the human is close or not without even looking for it. Also, if the human chasing, better to give the player a way to know if he is being chased and in a big danger (best way is also sfx I think rather than telling the player by text). I feel like if the human see the rat, it's nearly impossible to escape, because it is that hard to escape since their movement speed is really fast. One fun way to improve this game, is by adding a mechanic for distracting the human (ex: press E, then the rat will make a sound and attract nearby human to the sound loc). pretty nice game after all, good job!
