This is a game in which the UFO is just advancing to the depths of an endless cave.
How to play
Tap the screen to raise the UFO and avoid hitting the cave.
If you cant avoid the UFO, press the UFO button to enter invincibility mode, which allows you to avoid collisions for a certain period of time.
Use it with good timing.
