Evolving Shoot 'Em Up "GENETOS"
You can go through the history of the genre!

## What's the GENETOS?

GENETOS is a vertical shooter with an "evolution" theme. In GENETOS, the levels represent different generations in the evolution of shmups.

The 1st level. You start out with a Space Invaders-like game.
In the 2nd level, you move into late-eighties-style world.
The 3rd level is more standard. You get bombs and more firepower.
And the 4th level. Go to bullet hell!

When you shoot enemies down they drop green items. Collect items to fill a bar at the bottom of screen. When the bar is filled up, you go through a "Generation Shift" and your ship will evolve to next-generation model. The first model can only move horizontally, but the second model can also move vertically.

Collect green items.
When you get it to 800 points, the stage boss shows up.
You get 1000 items, your ship will evolve.
Defeat the boss with increased firepower!
In the next level, enemies have been changed, too.

Use the arrow keys to move, and press Z key to shoot. Let's try it!
