Playable. No major concerns with play however it does become boring due to the repetition of the game. Would have liked to see different types of units able to be spawned - ie: gold for cannon, or something to that respect.
Very easy, time and persistence will eventually break the enemy lines.
Not much creativity above the initial idea, very straightforward.
Map Design: 2
Well at least it is not default grass but otherwise no other map features.
Opening scene was well done, simple and precise.
Perhaps consider turning off chat features so I am not constantly reminded units are spawning because of wood tribute. Would be nice to see some different unit selection or maybe some upgrades (collect gold for upgrades or something) to change up game play. Enemy threat not great either, they do not seem interested in attacking back, would be a feature that could be added for better game play.
