Hi all,
I've been working on two important features. First one is the Tower Build queue. It will allow you to build many towers in advance without waiting for energy to become available. All your build and upgrade requests will be queued and executed as the energy becomes available. You can do this even when the game is paused. It's a lot of fun to just draw a line on the map and see a bunch of towers queued in a row. This feature will let you visualize your plans better.
The second feature is the Level editor. I already have a makeshift level editor that I used to design levels. It needs some work before it can be of any use to you. You will see it soon enough though.
For now, you can enjoy these screenshots from the planned Manual pages. The manual is for advanced players who want to understand the strategy part better and design levels of their own.
Terrain types
Enemy types
Tower types
Have a wonderful weekend.
Cheers!
