Fun game :) Really like the way you fit the theme by working together with your past corpses haha. I never did find the dog, since I found the jump timer very long and a bit frustrating.
Very much enjoyed the fact that your corpses have physics to them. The graphics are also lovely, though the camera could be positioned a little higher. I felt like there was a lot of dead space at the bottom of the screen. Maybe adding some verticality to the levels would improve this?
Solid jam entry!
