The web build doesn't seem to work, unfortunately. It completely freezes.

weird.
Is it freezing on the "press any key" screen? That probably should have said "click the mouse inside the window, then press any key".
The game pops up in a new window, which doesn't automatically grab focus.
But point taken: The web build seems to be causing more problems than it was worth. Hopefully you'll try the downloadable versions.
