Vibrant

Hotline Miami meets abstraction. Vibrant brings you "in the zone" through hyper-focus. Your last freedom is movement. Vibrant started its life back in 2002 as a short MS-DOS program. Curiously still alive 15 years later, it has turned into a quirky savage arena shooter I'm still learning from. The goal was to make Vibrant as hypnotic as possible. I think it specifically trains short-term memory, as the number of things to remember in combat may well exceed your capacity for recent events. If you feel overwhelmed, try to ask yourself the question "Can I focus more?". You probably can.
