For some reason this game was EXTREMELY laggy for me to the point of being unplayable. Even in the menu I was getting less than 1 fps! I tried to do some troubleshooting but I can't seem to track down the issue on my end. I also checked other browser games and they worked fine for me. Also, judging from other comments, I'm the only one experiencing this issue. Something about this game doesn't seem to like my computer specifically. I'll try it from another device as soon as I can. Until then, I thought I'd let you know about this in case it becomes a recurring bug.
P.S. I didn't rate the game badly for this. Once I actually get a chance to play it, I'll give it a good rating.
