I have seen other people talking about it but the web version is absolutely unplayable, for me, basically 5 fps the whole time. It's kinda nutty I'm on a portable PC but it's not some 2009 potato.
It's a real shame because the game looks really fun but if it plays like this, maybe there shouldn't be a web version, it looks like a fully fleshed out game, I'm sure it would be popular without a broken web version.
