Sine Of The Times: Waveform Demo On Steam

Clever wavelength-tweaking game Waveform - in which you must fit a wave to suit the incoming stream of, uh, things - failed to reach its relatively modest Kickstarter goal, but has nevertheless arrived in the mechanical innards of Steam. There's a demo on there too, so you can get a taste of what the thing is like before you choose to plunge headfirst into its attractive, wave-based challenges.
