The basics are there but its just a bore to play.
-Simple dual stick controls
-Well done heat mechanic (too bad it isn't actually used in any of the levels)
-Decently good fluid mechanics
-Shooter mechanics are moderately well executed, but not really implemented into the game. Although lightly present, has almost no effect on the majority of the game.
-Graphics are very simplistic but presented in a cohesive way. Not great, but certainly not bad.
-Permanent Pixel Junk banner in the bottom of the screen while you play. SERIOUSLY?
-Gameplay is very slow and tedious
-Boring level design (game has good mechanics, but the levels do very little with them)
-Ship accelerates too slow.
-It "feels" like a mobile/tablet game. (Ok this is probably just my feeling, but the level design, ship acceleration, and a few other menu aspects all felt like they were designed for touch based devices to me)
Most of the game is just flying around the levels picking up the humans and avoiding heat with the occasional bad guy to shoot at (with no real reason to since they respawn randomly anyway). In itself it isn't a bad concept, and the controls presented are fairly clean, but the game is just boring to play.
The shooter aspect is a complete afterthought in the level design and given the ships slow acceleration, most levels are just a slow trudge collecting the humans before an exit.
This could be a decent game if they incorporate the shooter elements and seriously ramp up the ships acceleration, but as it is, there are a lot better options out there. Also, that banner is really ridiculous. You don't need to advertise at me while I'm playing your game.
If you are looking for a really easy, super slow, casual game then this might be it.
But given the game's name and advertising, I can't recommend it for what it wants to be.
