If you ever sit at the computer, re-watching your favorite tv series, or chatting with your friends, and you need a game that will occupy you, but won't take all of your concentration, this is it.
I used to play minesweeper or free-cell on days like that. Now I play Offspring Fling!
It's a simple platformer, with numerous levels, puzzles, and a variety of obstacles. The goal? You are a small, furry creature, whose offspring (and a lot of it) got scattered all over. You need to find your babies, and transport them to safety (on your head, or by throwing them around). It's super cute, and the levels can get super difficult. It requires a lot of thinking and skill, and timing. But it's a small, simple game that you can pause at any second, so it doesn't take up your whole mind. I usually play it while skyping with someone, or chatting on facebook.
Plus it's super duper cheap. Or at least it was, when I got it.
The graphics are old school 16 bit. And there are OVER 100 levels. The soundtrack? As adorable as the game.
So if you're looking for something small, simple, and fun to do while you're waiting for a video to buffer, or something. Go for it.
