Very fun gameplay loop that had me strategising to maximise my score. The controls feel intuitive and smooth and the sprites for the players and the monsters look great.
One suggestion I feel might improve players' ability to score highly is for the map to expand a little bit as the monsters pick up speed, at the moment, once the monsters are moving fast, all of your players become cornered and you just have to do your best to stay alive. Great submission though, and I may come back to try to top the leaderboard.
Cheers!
