Thank you for playing!
I'm sorry to hear that you had such an experience when loading the web version. I'll include that in the disclaimer.
Hopefully I can sort out the performance issues for the post-jam patch/es.
I was originally testing it on a ThinkPad T480 on Linux with both Firefox and Chromium. Despite the performance and camera issues on Firefox, I didn't experience such an extreme situation like you've described.
Could you tell me your specs so I can maybe run a similar configuration in a virtual machine when I'll be trying to optimize the game?
