Pretty good. I made it until the third level (Christmas level).
The games present us with a dystopic vision in which present-day humanity is fighting an alien force. In an original twist, the player takes the role of an alien entity.
Clear anti-capitalist themes permeate this artistic vision. For example, the banking institutions are slowly replaced by pagan celebrations of Christmas, undoubtfully thanks to the socialist alien forces.
Gameplay-wise, the player is more successful by watching the mothership's health than its own. A clear signal of the power of collective action. Viva la revolución!
