What browser are you using?
google chrome, maybe wait for others It might be for only me
I tested it on chrome at it worked okay for me (the web version has some issues but it's still mostly playable). It might be an OS issue, I should be able to make an executable for MacOS and Linux if that would work better, I just can't test them.
OH! I'm a little confused, I need to click connections first. It works now!
