As a base concept, I really like it. There’s a lot to explore and build on here. I didn’t see this pack while looking through the assets, so that was a good find and a great idea for how to use it.
The twist of playing as the rat was really cool and unique. If you keep working on it, being the rat could open up some interesting gameplay ideas, like slipping through small cracks in the wall as shortcuts and things like that.
Also, such a good thumbnail by the way!
