1) I double checked all of the "how to play"; no mention of it anywhere.
2) I've never seen that as a loading pro-tip; I'll take your word for it. *shrug*
3) Figured as much. Nicely done, both in being able to keep those assets ready and being able to pull all the level data that quickly!
4) Thanks for considering my suggestion. I wouldn't say having the button hint appear until would be good. Sometimes you want to use it ASAP because of a break coming up or you just hit a multiplier power up. Trying to think of anything different or better and coming up empty at the moment.
5) I'm very much aware the D-pad is usable. However, it's a bit slide-y in comparison to having four distinct buttons. I did briefly try using it for kicks, but it was a trainwreck. Also, for fun, here's how I'm currently holding the controller to play:

6) Yeah, I couldn't think of anything that should be affecting it either! Only thing I could think of was the stage itself (maybe some of the background assets were causing lag or something) but the same stage in Free Play, different stages in Free Play, different characters were all problem free. A reminder that this is on the PS3 version, not the Vita (I do have one, just haven't installed/tried it there yet). If you're not able to reproduce it on your end, I'd be happy to take some video footage (I'll be doing some filming later anyways because...)
I just cleared Master earlier today and I'm looking forward to recording some score runs! (Got Construct as a boss on the first try, but I think that's because I've been playing the ever-living bejeezus out of the Expert chart).
Well, that just made my day. Slightly off topic question: Do we know if anyone's full perfect combo'd any of the Master levels yet?
