I don't know if it just me, but this game gave me some serious "Valve-like" vibe, which is awesome. The music, grabbing objects, puzzles, story and plataforming are all really well made!
Oh, and as stated by others, it would be nice to be able to skip the texts after you've already read them. But don't worry, there is no way I would remove a whole star from this just because of such minor thing!
This game was very immersive and I loved it, thank you for the experience!
TL;DR for reviewers: If you're a browser-only gamer, I highly recommend you to make this game an exception.
