Not sure if I was getting hit by the slow spawn bug. I made a few attempts at playing but no enemies ever appeared regardless of whether I placed the tower quickly or slowly.
Not going to rate since I wasn't able to actually play the game
Ah that's odd, sorry about that! I think both buying and placing need to be quick after the page loads for the workaround to work (ideally within 1-2 seconds), but you probably already tried that. In any case, thanks so much for trying and good luck with the jam!
