Basic dummy stub for the arcade game

Demo version. Incomplete functionality.
Intended to be used on desktop & laptop. Limited mobile use.
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

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 around 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, but i already see the limit of the configuration.
Turn off some orbiting planets to improve performance by a big margin.
