What is Reddit's opinion of The First Tactics Free (SRPG)?

From 3.5 billion Reddit comments

I can do you one better. How's no gameplay at all or screenshots of the game sound? And this isn't the only game I've seen that does this!

I'll bite, though my phone is bitching about the low space.

Can this be played offline? As in, if I have wifi and data off, will it refuse to start? Or is there a download at the start and it's okay after that? How about ads?

The 'simple' style of the battles reminds me of The First Tactics, which isn't a bad thing. I don't need full-size sprites to tell who's who.

Anyone able to recommend good TRPGs/SRPGs like The First Tactics or Final Fantasy Tactics that can be played offline?
