I think this could be a great game idea, "meaowing changes time". The presentation is great with the unique Pixel-Artstyle, however I think you could improve your game a lot by adding in some cooler design as well as adding in character animations (Click here to see a Tutorial).
About the wild card: I think it's alright, Gabe is implemented (in an unique Art Style!), however, he is only the player, and kind of lacks some general... "life" (I still gave a plus-point for the meowing)
Overall, I am loving the presentation (except the fact that there's no in-game tutorial and some minor design flaws on the project page), and I think this game would have great potential! I hope you can comprehend my rating.
Sincerely,
