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.
Blue cloud is the Fast Time zone - it's like a slow one, but, y'know, fast. All spells rush through it at twice the speed.
And that lonely green charge is a Laser Bolt - the most basic spell in our game. You fire it from your casting point and it flies in a chosen direction. If it hits something, whether it's wall of arena, some summoned object or even another spell, it gets deflected. It gets deflected too much - it loses its power and gets dissipated. It hits your enemy - it hurts. Really basic spell.
