Thanks for the feedback! This originally started as a really simple concept that I could make in a single weekend (though I wasn't able to finish it then), so I didn't have much more planned out than "eat cheese and run away." If I were to spend more time on development I can definitely see myself adding some more features, like what's been recommended in comments.
As for the mouse in the title screen, there's not much I can do about that since it's from an asset pack I used 😅. I'm more of a programmer, and tend to use pre-made assets to speed things up.
