I'm sorry this isn't working for you! It's a bug that seems linked to the play online version as far as I can tell - do you mind sharing which browser you're playing the game on? I've tested it through with Firefox and Safari without issue.
Had the same problem on my pc running it on whatever microsoft is calling their browser this week...
I played it with itchio downloaded on my computer
There are also free PC, Mac and Linux downloads of the latest build available both on my Patreon and also as links on TFGames and F95Zone, just fyi!
