By popular demand we've launched the Standard Edition of Spoiler Alert. Initially we felt like we should just release the Collector's Edition on Steam - justifying a higher price point. However it was a mistake. We admit that people need to have the option to buy a standard and collector's edition, doesn't matter which platform you're on.
So now the Standard Edition is out, and costs $2.99 on Steam.
It goes in-line with the estimated price we'll have on mobile platforms.
