Thanks a ton for taking the time to play it and write all of this up! A few of these actually line up with things I've noticed myself, especially the responsiveness, so hearing it from someone playing on completely different hardware is really helpful. The framerate/freezing issue is definitely going to be my first priority to dig into.
I hadn't considered ESC conflicting with browser fullscreen either, so that's a great catch. And I really like the idea of audio being more useful than just background music/SFX, especially using sound to help identify what's happening outside your immediate view. That could fit really well with some of the systems I'm working toward.
And yes, I'd absolutely love the VOD when it's uploaded! Watching somebody encounter everything for the first time would be incredibly useful. Thanks again!
I have PLENTY planned, but I'll try and have some self restraint and focus on the performance and such as you noted, lol.
