One of the earliest shooting games, Space Invaders, using P5.js.
- I can see a ship and different space invaders on start
- The aliens are constantly moving down the screen
- If the aliens approach the bottom of the screen, the game ends
- I can move the ship with my arrow keys
- I can shoot by hitting the space bar
- If I defeat an alien, I earn points
- If I defeat all the aliens, I can see another wave
Actually, I think in the original game the aliens are shooting too, so that would be a great addition.
