Jetpack Defender
How to play: Press Up, W, or click on the left side of the screen to boost upwards. Press space, or click on the right side of the screen to shoot. Shoot as many invaders as possible. When too many get past you, they swarm, and death is almost certain. Good luck!
I had to make a couple of adjustments to get this running on the web.
- When run on a PC, high scores are persisted by saving them to a file. As this is on the web, this is no longer possible. High scores will reset whenever you refresh the page.
- My system for multi-channel sound effects is fine when I run it on my home PC but very quickly runs out of memory in this web version. I'm using a less sophisticated sound system that has one blast sound effect at a time and one explosion effect at a time.
