Plasma Shooter

When the clear dark night sky suddenly starts showing green plasma balls flying back and forth, you may come up with a conclusion that it's not without a reason. Who knows? Perhaps some probable (potential) adversary is launching them for the purpose of sabotage and reconnaissance. Even if it proves to be wrong, we should bring the green plasma balls down. Luckily we have a brand-new high-strength armor-plated self-repairing tank with ecologically pure pollution-free firewood-fueled engine. Driving the tank has never been that easy. Just swipe a finger against the screen left and right. Don't take away the first finger and tap the screen with another one and you'll launch red plasma missiles which destroy the green ones upon collision. Beware the contact with green drops falling down, they are very harmful for out tank hull plating. Let's go and may the luck be with you!
