I love the concept of having to tap objects to see where you're going, but I couldn't seem to interact with anything? I assume I was supposed to pick up the pile of books on the floor but it did nothing when I hit E.  This could be a really cool game with some more time, I hope you expand on it!

Oh and when you're building a game, please make sure to exclude the SteamVR stuff, it opens SteamVR on my system when I launch the game otherwise xD

Very cool atmosphere and I like the echolocation (but it is a little hard to click off, you have to look at the ground). I was unable to pick up books though. Really like the particle effect and would love to know how you pulled that off.
