That dog's the best ! gotta say it right off the bat, i like how you never get stuck thanks to him and i like how in a sense you made it quite believable where he barked to get your attention then ran to the area of interest.
I'd say overall i like how much of a feel good game this is, and the low poly aestetic with just the right amount of detail is really cool too !
If i had to nitpick a bit i'd say the cave is a bit too dark even with the flashlight, cause when you're not close to a wall you can't see and can get confused as to where you are, but really small potatoes of an issue compared to how polished the game is.
Really enjoyed it, you did great, cheers :)
