Crystal Raider
50 rooms full of treasures await the brave yet thoughtful explorer in this
platform game. Using limited thrusting ability, you must collect as many
crystals as possible before moving on to the next level. Rooms have multiple
exits, leading the player to different segments of the screens.
You have five lives, and will lose one on contact with any of the nasties
which move around the screens, or when you run out of time (represented by
depleting oxygen). In either case, you are sent back to the start of the
screen, but keep any crystals you have collected. Collecting every crystal on
a screen earns you an extra life.
For an extra challenge, the game can be played in Night mode, which limits
visibility to the area immediately surrounding your character.
