This is an interesting game, and I enjoyed the top-down gameplay a lot.
I have to admit that I didn't read the game description or text prompts at first, so having a built-in tutorial would have been a little more helpful. Without one, it took me a while to figure out that I could clear the level by sneaking up from behind, and I only discovered the bat transformation at the window by randomly clicking around.
Overall though, it's a nice game and I can really see the effort you put into it. Nice job!
