Two very good games on offer for the price of one: Gremlin's Bounder and Planet Search.
Bounder is a great little game where you control a huge tennis ball (Bounder) bounding around a screen of hexagonal slabs until you reach goal. Blocking your route to goal are vast mountain ranges that must be avoided at all costs. The hexagonal slabs all serve different purposes. The mystery slabs, identified by a question mark, can be very useful when collecting bonuses, but don't be misled - several of them are bombs!
Other problems are exocet missiles and kamikaze stickits that hurl themselves at you and require quick reactions and careful route planning to be avoided. When the goal is reached, a bonus screen appears and you have to bounce on all the question marks to earn a big score bonus.
Bounder is a super game and one that will keep C16 game players occupied for quite some time.
The second game, Planet Search, places you eight planets away from home. The inhabitants of the eight planets in your way are intent on not letting you return home so you have to battle your way through. Shoot down the aliens, collect their eggs and, after wiping out a certain number, prepare to enter the space warp tunnel. This gives access to the next planet, but you must avoid contact with the walls if you are to enter this next stage.
Both games offer excellent value for money and the package is well worth the price.
