This is a very arcadey game, the kind I like, very easy to pick up and play, fast gameplay and based around scoring points. You play as an Alien(Called 'UFO' by the game), actually, you can pick from about 11 aliens, all of them equipped with the same abilities(Although their 'special pranks' differs between each other), but most importantly, with a Scan Gun. Y'see, aliens are pranksters by nature, but they are fragile and scare humans into attacking them, that's when the Scan Gun comes into play, with it you can disguise yourself as a human and play pranks on them! Pranking the humans makes them drop coins, the objects you must collect. Pranks come in very different flavors, from basic guns(Yeah, the pranks can get hardcore), to fireworks, bad singing, farting or tornadoes and... I don't know why some of these are called pranks. Regardless, pranks, even the deadly looking ones, only incapacitate humans for a while, and they also anger them, which makes them chase you. As a human, you can only take two hits before reverting to your Alien self, and taking hits without a disguise makes you drop coins. But it's alright, because you can scan humans even while disguised, and by walking below an UFO you can disguise again.
I give Under the Skin props for having an original idea, but it's far from a hidden gem. While the game's box boasts about '40 different pranks', the game itself gets old pretty fast. I think it has to do with how slow the game can be, while the gameplay is relatively fast-paced, the amount of coins you must gather is rather high, and considering you are competing against another alien, it can turn into a power struggle, which makes 'matches', or 'stages', go by relatively slowly. It also doesn't help that there's only 8 stages in all.
