[IndieGames.com: The Weblog co-editor Tim W. rounds up the week's top free and commercial indie games on his sister 'state of indie' weblog.] This week on 'Best Of Indie Games', we take a look at some of the top independent PC Flash/downloadable titles released over this last week. The delights in this edition include an adventure game that focuses on user-created content, a one-button Gamma IV selection, an Experimental Gameplay Project submission, a game in which you're the star of a survival horror movie, and a 2D platformer that will provide some challenge to gaming veterans. Here's the highlights from the last seven days: Game Pick: 'PlayPen' (Farbs, browser) "You've got to hand it to Farbs - everything he creates is stupidly awesome, and PlayPen is no exception. It's a world created entirely by the players and is constantly expanding as users build it up with their weird and wonderful ideas. There's various routes to take and paths to go down, and each leads to more pixelated scenery and ways to venture." Game Pick: 'Poto & Cabenga' (Honeyslug, browser) "Poto & Cabenga is a one-button game in which you control 2 separate characters. It works as follows: pressing down the space bar makes the top character jump, and releasing it makes the bottom character jump. While the space bar is held down, the bottom character will run forward while the top character falls back, and releasing the space bar will yield the opposite results. Sounds incredibly tricky, yet it's really not that difficult at all." Game Pick: 'Linepatterns' (Erik Leppen, freeware) "Linepatterns is a puzzle game created by Erik Leppen for submission to the Experimental Gameplay Project game development event, where the theme selected for this month is 'Repeat'. The objective here is to fill up as much of the screen with multi-coloured lines as possible, since new puzzles are only unlocked if the average screen filled percentage is more than sixty percent for all previous levels." Game Pick: 'Zombie Movie' (Edm Games, freeware) "Zombie Movie puts a great twist on the rather tired zombie-killing genre. A helicopter flies overhead, filming your every move, while you plough your way through hordes of the undead. Move too far away from the helicopter, however, and you'll find a fate worse than having your brains eaten. That's right - you'll get fired." Game Pick: 'Quietus' (Time, browser) "Quietus is a tough platformer which feels like a cross between Meat Boy and the castle levels from the 2D Super Mario games. You play a guy who has hanged himself, then been throw into a gauntlet in Hell by Death."
