So I used to play this fun, addiction game and now I forgot it. I remember there is a 2d map. The map has "spawners" spawning purple slime that fills the map. Your goal is to protect a "city" block on the map and connect it to lasers, mortars, etc. To escape the land (spawners are indestructible) you must power 3 totems on the map which will then open a portal for the city to escape. There were multiple maps and levels published daily. Can someone help me find the name? For more info about the game, just ask in the replies.
