Every game has a prototype, a small model that demonstrates how the final product plays. Here’s the prototype to a PSP game Every Extend Extra: Every Extend. A game with hypnotic music and pop visuals.
Fun at short bursts, Every Extend can be downloaded here.
Every Extend plays like a randomly-generated top-down shooter. Unlike top-down shooters, though, the only way to kill enemies (blocks) is by exploding yourself. If you manage to hit one, that enemy will explode, hitting any enemies near. By this simple chain-reaction, you attempt to extend your combo to the largest number of enemies possible. Certain colored blocks give you different power-ups: red ones increases the number of enemies, green gives you more ammo, and yellow gives you more time.
