In ZType, you never see two ships starting with the same letter at the same time, so once you start typing the name of a ship, the game focuses on that particular ship and all the letters you type are assigned to it.
Even in the hardest moments, when you're surrounded by enemy ships, you still have a chance to make it. You can use special bombs that let you destroy all the enemy spaceships nearby. That being said, you only have three bombs and the enemies are many.
ZType is a good spaceship game that helps you type faster on touchscreen devices. An excellent combination, and it also happens to have nice graphics.
