What is Slime Trader?

In this free-to-play, single-player defense game, you summon random slimes and position them outside a pen to shoot the larvae inside. Stages contain five rounds and bosses, while equipped runes modify combat and resource gains. Rebirth restarts stage progress and grants points for drawing more runes, but preserves your slimes, gold, and summon cost.
