XNaCAVE

## Description

_XNaCAVE_ is a horizontally scrolling cave flyer. The space ship
automatically flies forward and the player only controls thrust by pressing an
analogue button: the ship goes down when letting it go and goes up when
pushing it fully. Being steady requires to hold it in the middle. By using
this thrust mechanic, the player needs to avoid crashing into the edges of the
cave as well as obstacles in the way. Each hit ends the game and saves the
high-score.

However, the player has one ace up the sleeve: by pressing another button, a
shield activates which protects from hits. This drains resources from an
energy bar, but it automatically refills over time. Occasionally there is an
earthquake which shakes the cave and therefore makes it harder to avoid
obstacles.
