Cyberkast is a multiplayer free-for-all and dueling game, aimed at groups of 2-6 players wishing to have some seriously chaotic fun. Genre-wise, it combines elements of arcanoid, billiard, pong and even a tint of tower defense or strategy, resulting in a mix of arcadey and logical goodness. Flavour-wise, it's about deep space duels of cybernetically enhanced transhumans whose control over time, matter and energy has started to resemble sorcery.
Now we get to the older screenshots, where lots of things are already obsolete. As you can see, we've implemented new casting gates (the point where your moving spells are summoned at), rescaled the arena, changed lots of graphics.
One actual spell here is Forcewall Pylon (graphics need an upgrade, though) - you place two pylons together and wall of pure energy appears between them. Pylons are them are destructible, but wall is invincible.
