So I don't really want to rate this since you didn't finish. So bugs and lack of content are no big deal--you can finish that stuff later. But I couldn't help feeling misled by the title, the cover art, and the fact that it's entered into Adventure Jam, all of which had me expecting, well, a murder mystery rather than a side scroller.
I do think your art is great--the girl and the slime mom both had very expressive and good-looking animations.
