How's Offspring Fling? Thinking of getting it.
I really like it. It's got a lot of charm in the graphics and the puzzle mechanic, while maybe not particularly new, works well. If feels like the kind of game you'd play on a handheld(like Popils, Pushmo, Carrier or those types of games) and it's nice to see that kind of game on Steam. If there's one thing that bothers me, it's the halfhearted joypad support, something that seems typical for PC games. Sure, you can control the game with the 360 controller, but it defaults to the analog stick and trying to navigate the menues, will have you reaching for the mouse.
That aside, it comes recommended.
