Strange Invaders

Here's a game featuring weird and kooky aliens that everybody needs in their life. Playing it strengthens your pattern matching, reaction time and short term memory. Strange Invaders has a retro feel to it, and, well to be honest, it should probably be banned for being so addictive and fun to play!
Winning at Strange Invaders is easy as pie. Simply tap on the flying alien that matches the alien drifting across the bottom of the screen. Avoid touching wrong aliens, though, as that results in a penalty of 10 points. UFOs are even more perilous at minus 30 points.
You can play for free up to level 5, but in-app purchases will unlock an additional 25 levels and new mini-games.
Between levels, there is a mini-game for more bonus points, because who doesn't like mini-games?! Go, Team Earth!
Try to set the high score, and save the world from the comfort of your armchair. You got this, Supreme Commander, Planet Earth!
