Page content

UPDATED ON: 2025-11-28

Dangerous Dave is a small demonstration of JavaScript capabilities.
Control Dangerous Dave in wacky space riding green glowing blob by means of:

  • [▲] [▼] [◄] [►] arrow keys for movement
  • [Spacebar] for laser shot
  • [F8] to turn on/off orbiting planets
  • [Enter] to become as cool as Duke Nukem

▀ FEATURES

  • no heavy frameworks and dependencies, just pure JavaScript
  • compact size, less than 500Kb including graphics and audio
  • tiny core only 35Kb!
  • completely free, no license, do with it whatever you what

More stuff to come (why we have only 24h per day?).

▀ GFX NICETIES

  • multitude of space backdrops
  • static stars [layer1], moving and rotating with transparency [layer2]
  • random blinking [layer3] and moving stars [layer4]
  • “raining” moving stars from top to bottom [layer5]

▀ TODO PLANS

  • improve performance if it is possible
  • finish mobile version
  • ….TBD….
  • ….

▀ DONE STUFF

  • beta mobile [touch] support
  • add sounds to startup, actions and backdrop ambience
  • make Dave leave trace while moving
  • implement space bar fire
  • make Dave to turn arround to the direction he is heading to
  • random starting location of blinking stars, they also should change their formation upon blinking

▀ TECHNICAL DETAILS

Ultra low-budget i3-3220 from 2013 runs it quite decently.
Turn off some planet orbits [or turn them off completely] in markup to improve performance by a big margin.
