The title is pretty self-explanatory. I need ideas for enemies and towers for my tower defense game. I already have a few, but I really need some creative ideas to help my game stand out. Thanks! 
What about an enemy that sometimes drop a lure that has a lot of life but not speed nor damage, and just make low level towers focus on it? I’m not a big player of tower defense games but I hope you’ll like my idea.
Also, what about a tower that lowers the enemies speed? I’m not sure if these ideas are already made but at least I’m trying.
