Surprisingly enough, the game is now available for purchase at the
Humble Store. While this is of course great news for anyone who missed out on March's Humble Monthly, I have no idea why Nifflas decided to keep it a secret until now.
Given how vague he'd been about this before release, and the fact that past Humble Originals have apparently always been available exclusively through Humble Monthly at first, I assumed it was going to take a while before the game would become available for purchase directly.
In fact, I think I recall Nifflas claiming that as well, but I can't say for sure because I haven't been able to find the tweet in question again. Either he deleted it, or I'm mistaken about this.
This is pretty annoying for me because it means I ended up paying about $4 more just to get a bunch of additional titles I have no interest in.
I hate to say it, but Nifflas has got some explaining to do.
