Trivia

Although it’s simplicity, there is actually a lot of complexity in this game which started to use more advanced programming concepts.

Like most of the previous games, it focuses on having the best score. There is 3 different kind of collectibles for this:

• Coin (10 points): can be anywhere in a cave section, will lead to a safe path. It will be destroyed in contact of the spaceship laser
• Diamond (150 points): only spawn above a cave block (with 1/16 chance)
• Gem: found in harder to reach places in cave section. There is 6 different gems that can spawn:
  • Blue Sapphire (200 points): 50/182 chance
  • Red Ruby (250 points): 40/182 chance
  • Purple Pearl (300 points): 40/182 chance
  • Green Emerald (400 points): 30/182 chance
  • Gray Diamond (500 points): 20/182 chance
  • Multicolor Opal (1000 points): 2/182 chance

From a game design point of view, I had this idea of different cave section chosen randomly with a same start/ending for a smooth transition. There is a total of 10 different caves (with one unfinished and unused) chosen randomly.

Another system that I was pretty proud of is the mechanic to calculate the distance travelled. Basically there is a hidden vertical bar that follow the spaceship vertically and move backward whenever the spaceship touch it which increase the distance.

Some blocks are a bit lighter, similar to Smiley Adventure where touching this blocks will destroy them, here you simply go through it which can lead you to secret path with gems

I also add a complex system of “deactivation”. Some objects such as coins are deactivated when outside the camera view to avoid using too much resources. My first step towards optimisation in my games.
