Genetos is a vertical shooter by Tatsuya Koyama featuring stages with design styles from different eras of arcade gaming classics. Green power-ups would have to be collected to increase the gauge at the bottom of the screen and ultimately culminate in the evolution of your ship, where it will gain additional firepower, new movement directions, bombs and even homing lasers.

Use the cursor keys to move your ship, and tap the Z key to shoot. Press the X key to launch a bomb if available. The current build contains four playable levels. (source: Shoot the Core)
