Intence game! I think that's a great solution for a tower defence with one tower! You have to think and you have to switch. And you can't juse see and wait enemies to be killed.

Thanks! It does definitely turn the typical tower defense strategies on their head.
As for the style, I'm sure there are tons of ways to accomplish it. What I did was make the models in Blender and I used the inset feature to add rims around each face. Then I used vertex painting to set the faces to black and the rims to white. Then in Unity, I created a shader to use the vertex color along with a property color as the emission color. There is also a post processing volume with a high intensity bloom filter applied.
