My no‑commentary playthrough:
I really enjoyed the atmosphere and quiet tension in this game. The contrast between the bright daytime playground and the dark underground bunker was great, and the restraint on the scares made the whole experience feel more unsettling in a good way.
One small thing I ran into was the butterfly moment. Since it appears halfway through the game and introduces a new mechanic, it took me a minute to realize I needed to follow it to progress — probably just me, but I figured I’d mention it.
If I had any suggestions, it would be to add a bit more story or context leading up to the ending — maybe a few extra interactions like keys, doors, or additional drawings to deepen the mystery. Overall though, this was a great experience. Quiet horror is my favorite, and you nailed it.
