Spoilers are in this comment
The first and second run I did, I somehow killed myself while jumping on top of a box, similar to what happen in Gmod and other Source games sometimes. These runs were me slowly walking around trying to figure out what to do. The next run I finally figured out I could shoot the pot and got the house key. I then somewhat quickly figured out what to do next, but couldn't figure out the candles until I looked at the other comments. I couldn't figure out what to do past this point, which leads me to the stuff I did like about the game.
Swapping between the dog and human was a really cool feature that I liked. The visuals looked great, and the sound design was on point. Having a pet in a game always is a plus to me. With a few changes (more obvious what to do next, less motion blur, faster movement), this could be a really good game!
