Thanks for playing! Glad everything worked on the Vive as I no longer have mine to test with lol.
For the robot effect, the main thing is to stack up delay, it's kind of like a really quick echo, makes it sound so crunchy. Another major component in the sound was a high & low EQ curve that I used to make it sound less rich and as if it was coming from an intercom.
For teleportation I just used the SteamVR plugin's already made system and placed invisible collision planes everywhere the player can teleport to.
Anyway, thanks again for playing & rating! I plan on playing most all of the games, I like your trailer so I'll definitely play it in today's session.
