I really wanted to build a WebGL version, for the exact reason you mentioned. we had used Unity High Definition Render Pipeline in order to learn how to use it in this project. Unfortunately, HDRP is not compatible with the web build. I would love to go back and make one with the standard Unity render pipeline so that we can have a web build. 

I am really happy you enjoyed the game, I think my team did an excellent job.

Thanks for the feedback, I am glad you enjoyed it. We actually caught that bug in development but decided to keep it in since it was kind of funny. Like we thought that maybe the teacher would think you were studying more at the cost of obscuring your screen. But I do agree it does not really make the game fun, I think if we were to properly add it as a feature (like maybe if it didn't block as much and gave you extra time to answer) it could be interesting.

That makes me so happy! When we set out to make the inner game, we wanted to go for a Doom sort of feeling, so to hear that it felt like Quake makes me feel like we did a good job emulating that feeling. 

I am really proud of my whole dev team, our artists and musician totally nailed it imo. 

Just so you know, dying in the inner game does not actually mean it is a game over, it just reduces your final score at the end so you can still finish the game and get a presentation grade. But you will need to not die or miss any questions to get that juicy "S" rank ;)
