  • What is the weapon of the shark?
    • laser beam
  • How does the shark shoot lasers?
    • with his fin laser
  • How does the laser affect the opponents?
    • blows up space ships
    • damages shield (on more advanced ships?)
  • How do we limit the usage of the weapon? How is the health of the shark counted (what causes a "game over")?
  • When do you win?
  • How do we increase the difficulty as the user plays?
  • How do we count the score?

Open Questions

  • Do some spaceships move faster than others?
    • Maybe it depends on the color of fighter (green 💚 slow, blue 💙 medium, red ❤ faster)
  • Do the spaceships fire lasers back at the shark?
    • Yes, the shark has health (three lives ❤❤❤)

Power-ups

Currently, none.

Suggestions

  1. Speed-up the shark's vertical movement (jetpack?)
  2. Increase the shark's size (fish?)
    • Chomping an enemy gives 10x points
  3. Slow down enemies (clock?)

Power-ups last 10-20 seconds, to be determined.

Score counting

Currently, game starts with 0 and increases for ever enemy hit.

Action Items

Starts at 10 points and decreases by 10 points whenever a UFO passes the shark, negative points cause game over.

Health counting

Currently, game starts with three hearts (❤️❤️❤️) and decreases when an enemy goes past the shark.

Action Items

Game starts with three "planets" (🌎🌍🌏) and decreases similarly, as if the enemies are destroying the planets, or something. Each "planet" could have segments, between 2-4 perhaps.

Shark has three lives (🦈🦈🦈) and decreases if a UFO hits the shark. The third hit causes game over.

Difficulty increase

Factors

  • shark gun charge speed (1% / tick but slows to 0.5% / tick during 1 min) (see point 1 below)
  • enemy spawn interval (every 4 sec but increases to ever 1 sec over 3 mins)
  • shark movement speed (currently fixed)
  • enemy movement speed (currently fixed)

Action Items

  1. ✅ Remove gun charge (needlessly complicated)
  2. Difficulty should increase as you keep playing
