It looks way too simple to be a finished product. As a gameplay prototype it works, but there aren’t any details. Try adding more interesting shapes and colors. Maybe make a good looking lobby with a round system as well.
Also, the thing in the bottom right corner looks low quality and pixelated. “Wait before sending a emergency” doesn’t flow. I would say “Wait ____ seconds before calling an emergency.” Or better yet, make the icon gray and put a big white number over it that’s counting down. The player should know how long they have to wait. The less text you have the better.
looks good, but the map is empty and few people will be interested in looking at empty rooms, revive the map, add something to make it seem that the map is not empty, everyone can put walls. I wish you luck. : D
