I have noticed a definite increase in views over the past 24 hours, in fact it has been the best day so far. It looks like a lot of that is from facebook, so thank you both. I have also been promoting it in more technical places, such as the libgdx reddit, as AGILE uses libgdx, and the gamedev.js newsletter. I'm going to think of a few more like that. Maybe things like webdev and javascript on reddit, but focus more on the tech used, e.g. certain browser APIs, as a way to introduce and link to the app. - Someone in the libgdx reddit was happy to have been able to play Tetris on their phone. Not sure which of the two Tetris games that was.
Yeah, I agree that bringing the subject back up under comments, etc. in relation to something related but new is avoiding being spammy. Thanks for the efforts.
The github stars have increased from 5 to 9 since the launch, so a few people have been looking at the github page as well.
