Really love the art style. I died at one point and when I loaded in again, none of the slimes spawned again. Also, I wasn't sure if I was doing any real damage to the slimes and wasn't able to kill one.
Thanks, dude! Yeah, I forgot to set a reset for the spawner! You are doing damage but with the basic sword, its only 1 damage and the slimes can be 1-50hp so it can take a while.
