Really just a snake reskin. It might work better if you made the mice move a little (try to get away from the snake), and perhaps made a bigger, scrolling map (using heat sense for radar or something)
If I may make a suggestion, if the point of the aiming line is to help people make better shots, it kind of defeats the purpouse of having help with aiming when your aiming line blends in with the background. May I suggest either changing the background color or changing the color of the aming line?
It's an interesting concept, but it's also one that you've largely wasted. You should take this concept and turn it into something with more depth. A lot more depth.
Great start, now just needs to be refined into a really great game. Maybe some extra monsters, some opponetns, maybe some refined objectives, but yea, this really has the potential to become a beyond terrific game.
