I'm glad you like the changes! It's much closer now to my original vision, it just took some time to get there. Yes, you can technically make funnels and kill boxes with any defender, but the purpose of the walls is to make something with lower maintenance that you can use for part of your structure. I like to build a "back" with walls, then use knights for the sides and front so I only have to keep a close eye on one place. You can also line the outside of your walls with archers if you don't mind replacing them periodically.
I'll be adding stats in mouseovers to the defender cards, but currently it's:
- Archer: 2hp, shoot speed 1, range 7
- Knight: 5hp, shoot speed 3, range 1
- Wizard: 1hp, shoot speed 2, range 5
They will spawn outside the map sometimes, I'll prevent that at some point, but for the moment the game actually periodically picks them up and drops them somewhere inside the map, so they won't build up out there.
