I tried playing this game, my first impression was confusion. Is this a tower defense game? I couldn't find anywhere to place machine guns or other defensive structures. I saw brownish, flowing (or perhaps air currents) reaching my tree, but I didn't know what it was—was it an enemy? What was its purpose, and should I defend against it?
I saw some enemy-like things approaching or entering the tree. I hadn't even had a chance to do anything, but I completed the level.
This doesn't feel like any tower defense game I've played before.
I think a guide is needed, at least to tell users the purpose of each level and what they should do.
