I think this game should be inporved because it takes a long time to load and it keeps crashing when I waiting to be loaded.
I've noticed that some browser games including this one sometimes seem to stop loading completely. This game is pretty big, so it might take a little longer to load, but when the loading seems to freeze for a long time, refreshing the page has helped me in the past.
I might provide a desktop version to dowbload instead of this browser version in the future, since the browser version seems less stable.
Thanks for letting me know!
