Does this game speed up over rounds? I honestly can't totally tell but I'm now 2+ hours into a session on Endless Classic and don't really think I'll hit a wall unless it speeds up significantly so might just bail since I think I've reached all the achievements. I remember on Live once you get into rounds 4+ it would get pretty damn fast but can't really perceive that here. I mean I've been playing for a couple hours and my eyes are now bloodshot af...so great that's Lumines...but probably no point continuing if I can literally just do this forever.
One nice thing was that the game crashed on me about 100 minutes in and I was pretty much going to never play it again because forget that, but got back in and it let me continue even off an app restart. Whoo!
