Intact

_Intact_ is a vertically scrolling shooter. The player uses a space ship to
fly through four levels. Of course there is a lot of alien opposition to be
blasted away with the built-in gun. Every time a full enemy formation is shot,
the game rewards it with a credit symbol which needs to be picked up in time.
From time to time the player visits a shopping passage in which extras can be
purchased from those credits, e.g. a turbo boost, extra lives or weapon
upgrades. Those upgrades to not vanish after losing a life. Using a smart
bombs also cost credits but don’t need to be purchased first. The plot centers
around the need to defeat alien invaders.
