It’s Friday, so we like to highlight a few current app and game sales taking place in Google Play, just to make sure you all have something to play with over the weekend.

This week, Madfinger Games has a few of its titles up for grabs, including ShadownGun (plus the THD version), as well as Samurai II: Vengeance. In addition, star gazers can pick up Mobile Observatory for a lowered price, and multi-taskers can get Link Bubble Browser Pro at a discount.
