After a very unproductive Saturday, I started to make an enemy system and a way to continuously spawn them. Currently it is only aliens, but I will add more enemies for the other themes over the course of the day. I’m imagining a mixture of all the themes for your enemies, and different heroes are better against different enemies, whether or not they are from the same genre. For instance a sword attack is good against these aliens. Thinking kind of like Pokemon types to force you to use all of the characters.
