I keep getting ads for this on Facebook. Anyone know anything about it?

This is the first I've heard of it. There's some video of it on YouTube here and a page about it here.

Thank you, Marian, I found that, but not clear about from where I'd be downloading and if it's truly free to play or just free for a trial. The video is included in the Facebook ad.

Apparently you can download it here. There are also some customer reviews on this page which explain some things about the game.

It is a typical Free2Play game in which you can play in bits and pieces to progress and wait for your energy to charge, or you can pay to advance.

Thank you, Ana. Do you know anything about the source?

ETA: Read a number of complaints on developer FB page. Looks like free play is pretty short with long time to refresh. Think I'll pass on this one.

"Free to Play" is a misnomer, for sure. ha ha "Free to be Frustrated," more likely.

I tried a couple of them, and found them enjoyable, challenging at times, and they drew me into their game world, but you can play just long enough to get interested and then "Boom!" ~ your time is up. By the time you wait long enough to rejoin the game in Free Mode again, you are likely to have forgotten where you are and what you were doing. I have tried half a dozen over the last couple of years, wishing and wanting to see a bit more latitude creep into them, but never observing the reins being loosened.

It is great that some people enjoy these games, but they are not everyone's cup of tea.
