Holy moly, thank you SO much for such a detailed and kind comment. It means so much to me.
I'm thrilled that you had a fun time. It's exactly what I was going for - a kind of twitchy Quake 1 boomer shooter feel, but also some quiet stealthy exploration when running low on health.
And thank you for the MP3 bug report - I was preloading music to prevent any lag spikes but some browsers interpret it as a download request, and I'm on Mac and didn't spot it. Fixed now, sorry about the confusion. Let me know if you play and it triggers at all.
Again, thank you so much, it means a lot to have someone play and leave genuine feedback, especially a game developer too. Good luck with your games!
P.S. if you're curious, here's what the original game was like - it's also on the TV when you walk into the house as a little easter egg ;)
