This was way more fun to make than I thought it would be. I really enjoyed this theme. I choose to combine the battle royale with turn based fighting. Here is a short trailer for the game

Description

You are trapped in a dungeon with other slimes. The rules are simple, only one slime can leave. Time is precious, as there is poison slowly creeping in from all sides of the dungeon. ​You must hurry to defeat them all and become the sole survivor, or die a painful death.
