A nice looking game, giving vibes of Journey. I feel like this game needs a sprint button to walk a bit faster. The beginning felt a bit slow. Finding ALONE is the best part for me, it is really well animated (looks like a lot of the effort went on him, he is REALLY well done). Platforming felt a bit clunky and unresponsive. I'd suggest making the platform colliders a bit bigger or giving the player a bit more time to jump after he leaves the platform.
Sound was really bad but the creator says that the audio at the browser version is bugged, so I guess it should be ok on the downloaded version. Everything else was cool and well done. Overall great job!
