Hello everyone !

No big deal, but here is my first "original" 2D game: PWM (Pulse Width Modulation)

Basically, the goal is to press or release the space key to generate square wave pulses (in blue) and keep the white small ball on the screen (representing the speaker diaphragm's level) as close as possible to the yellow wave.

The ideia was based on this video

Implemented in java 8 using just standard libraries (java 2D, Swing, AWT), so no external libraries required.

Keyboard Controls:

[Space] key: move the ball up or down

Thanks Smiley !

Any chance of:

a) fullscreen/resolution change
b) rebindable inputs (specifically, use a mouse button instead of keyboard key).

It'd make it a lot more tolerant of hardware variance. (and would eliminate a couple of excuses for me being so bad  Pointing)

I don't know about that, but different key instead of space, would be nice, like CTRL.
