This variant take on the classic arcade shooter ala Space Invaders and others keeps things pretty simple but as you progress manages to consistently change things up a bit. Your default character and gun are very straightforward but as you collect thumbs ups dropping from slain enemies and eventually genetic modifiers you’ll gain power-ups that will temporarily juice you up and allow you to do more damage. Probably my biggest complaint is just the lethargic pace you tend to move with, making this a better recommendation for people who enjoy a milder action challenge than those looking for intensity.
