Independent video gaming showcase IndieCade once again has a booth setup at the E3 Expo, previewing a selection of titles from its upcoming IndieCade 2009 Festival slated for October.

Some of the titles at IndieCade's E3 booth this year include Independent Games Festival finalists SnapShot and Mightier , as well as IGF's Seumas McNally Grand Prize winner Blueberry Garden.

If you're dying to play Blueberry Garden but aren't able to stop by the booth, you'll be happy to hear that developer Erik Svedang just announced that the interactive fairytale will release via Steam on June 8th. Here's a quick description of the PC game if you're unfamiliar with it:

"Blueberry Garden is a short and experimental game about exploring a strange world. It is set in an ever-changing ecosystem and your goal is to find out what's going on among the softly swaying trees and mysterious creatures living there. The game is a relaxing, yet intense experience for people who like soaring through the sky."

One IndieCade-featured game that you should set aside time for to try out during your E3 visit, though, is Octopounce, Anna "Auntie Pixelante" Anthropy and artist Saelee Oh's multiplayer game specifically designed with crowd environments like E3's in mind. In Octopounce, up to four players control different colored octopuses that work together or against each other to catch fish swimming above them.

Here, she explains some of the design decisions she made before debuting the game at Game Over/Continue? last April:

"Because of the nature of the event -- game controllers would be passing hands quickly between members of a large crowd of showgoers -- I wanted the game to [accommodate] changing players as easily as possible. When a player puts her controller down and walks away, her octopus falls asleep. Sleeping octopodes drift through the waters, acting as both obstacles and launching platforms to other players. When someone picks up the controller again, the octopus wakes up. The game runs continuously, regardless of how many people are playing it: octopodes who aren’t being played are simply sleeping.

I eschewed a numerical score tally, thinking it would cause too much attachment of players to their octopodes (you don’t own your octopus, you’re just borrowing her). So score is simply marked by the brightness of the octopus -- or rather, the opacity. A sleeping octopus is fairly see-through, but an octopus who’s catching lots of fish is solid. I put a text scroll on the bottom of the screen to periodically update players on who’s doing best. It also welcomes new players and explains how to play, helping new players to join without disrupting the game."
