THAT WAS SCARY. I should have expected it though, since 1. it's a horror game, 2. I get very scared by horror games, and 3. it's VR. When I died to the wardrobe monster, it felt unfair since the game didn't tell me what was happening or how to defend myself, so it felt cheap. I know that technically this kind of teaches the player how to play, but it's not fun here because failing means getting a huge jump scare out of nowhere which put me in a bad mood.
Anyways I got to round 4 or 5 before losing in the computer game, and I was too scared to try the game again, haha. The graphics in the runner game are great, good choice having totally different scenery in each stage. And the game itself is fun.
Overall the game has a good concept and executes it pretty well! The game has a nice flow (minus what I said above). The sounds and lighting effects are well-made and well-timed. The monster sound effect when you lose was well made, but personally I think it may scare people way too much - the creepy room sounds, the lighting, the anticipation, and the red eyes already convey the mood enough, imo.
Also, I'm a noob at using my cardboard, but the magnet slider didn't work in-game, I had to reach in with my finger and touch the screen. Also that's impressive you didn't use an engine! You should add a link to the source code. Also, I'm pretty sure there's software you can use to record gameplay footage of your game, haven't used it myself but I've heard about it.
I hope you find my comments helpful. Great job team!
