I'm glad you like how it looks. As for if I can make a browser version...
Short answer: No, sorry
Long answer:Took a quick look at the result of a html5 export. It technically functions, with some minor visual bugs and collision bugs. Most notably though the framerate slows to a crawl in anything except the smallest rooms. Tried some low-hanging-fruit optimisation but didn't make much of a difference. Could probably make it work but it would require a big overhaul.
