That was really cool! My first run they ran into the boss right away and one of the characters ended up getting stuck in the black space so I died... next run I managed to run into 1 group of little guys before finding the boss. The boss tends to spawn in the first room a lot it seems.
I was a bit confused on which names referred to which hero, I could kind of roughly guess but not 100% and sometimes I wasn't sure if the tanks were taking more damage or if the healer was getting aggro'd
Thanks for the feedback!!
Yes I noticed the spawning is a bit inconsistent, I think having a bit more structure to the spawning would make it more enjoyable.
I also agree with the names, heroes and health bar, there is definitely some UI work that could be done there to help improve the readability of what is happening.
