Dang a whole feline detective adventure packed into a game jam! Impressive work right here. The game looks great and plays good. Didn't experience any technical issues on my end. The story is long-winded, wish it was broken up with more clue gathering and gameplay. Subtitles would indeed help a lot too, and honestly with the spirit realm thing going on, and platforming gameplay in general, what an excellent opportunity to change the geometry per realm ala Legacy of Kain: Soul Reaver!
Anyway, really really liked this one. It came out great and really highlights your Godot expertise. Well done!
