I really enjoyed what the game has to offer so far.
i can not wait until vehicles and planes are added to the game.
In my opinion the game would would definitely benefit from different game modes (Defending for a certain amount of time or certain amount of waves) and a few different maps, each with a different layout that favors the using of different units and tactics to stop the game from becoming reputative.
Im excited to see where this game goes and can not wait for the full release
