[Every week, IndieGames.com: The Weblog co-editor Tim W. will be summing up some of the top free-to-download and commercial indie games from the last seven days 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 goodies in this edition include a Ludum Dare 20 competition entry, a 2D platformer that encourages players to rebuild stages, a Unity-based arcade game with balls, an unorthodox defense game from Japan, and an arena shooter where you control two characters at the same time.

Here's the highlights from the last seven days:

Game Pick: 'Officer Alfred' (Arvi Teikari, freeware)
"In Officer Alfred you play as the titular character who has to escape from a research facility after it had been discovered by the enemy, guided along by a voice that's coming through the building's PA system. The game features a time shield gimmick that prevents you from getting hurt by the complex's automated defensive weapons."

Game Pick: 'Money' (Enokitake, freeware)
"By the Power of Money is a 2D platformer that encourages players to rebuild a stage as they play, buying and laying blocks with unique properties while trying to keep their spending budget under control."

Game Pick: 'Ball on a Wall' (SmallGreenHill, commercial indie)
"Ball on a Wall is a Unity-based arcade game in which the player has to guide a ball towards randomly-appearing pickups, using only a limited number of blocks that can be pulled out of the wall to prevent said ball from falling off the screen."

Game Pick: 'Warlock Card' (Yoko, browser)
"Warlock Card is an unorthodox defense game that mixes RPG and card-based strategy elements together. You assume the role of a powerful wizard who has the capacity to remember just four spells in his mind, standing firm against whatever adversities that the enemy force decides to send your way."

Game Pick: 'Grief' (Magnesium Ninja Studios, freeware)
"Grief is a puzzle platformer that features twenty levels to play through, where the gimmick revolves around using special platforms to switch between light and dark worlds. The objective of the game is basically to collect the teddy bear found in every stage before guiding the young girl to the exit."

Game Pick: 'Collte's Spoon Devil' (Q Handmade Games, commercial indie)
"Collte's Spoon Devil (Koruruto no Saju Akuma) is an arena shooter with an interesting gimmick: you control two characters at the same time, each with their own set of health meter and weapon. Both of them can get hurt, but you will only lose the round if the witch Collte loses all of her health."
