Really liked the sanity hook here. Petting BUDDY actually flipped my character's face from a nervous grimace back to a grin, and when I let stress climb the expression went dizzy/hallucinating, so "only BUDDY can keep you sane" pays off mechanically instead of just being flavor text. Clearing the first mutant and pushing on ran smoothly, no hitches. One suggestion: an on-screen arrow or ping toward the exit door would help, since I wandered a bit looking for where to descend. Nice dual-theme read on DIVE + BUDDY. (I took the ocean route with DEEP for this same jam. Funny how many of us made the buddy the reason you can survive going deeper!)
