Really good... but there can be quite a bit of lag – DanceRailRefresh Review

I really appreciate the fact that someone would take the time to make a rhythm game that boasts a LOT of songs, without the user ever having to pay for any of them OR watch ads! However, on my old-ish iPhone 5C, the constant BRIGHT FLASHES from hitting the vast majority of notes causes my frame rate to drop regularly below 40 FPS, and I have seen it go under 30 and even down to around 20 OR LESS in the most severe cases! This, of course, makes it harder for me, on my old-ish phone, to hit notes accurately (or even at all!). If there was an option to reduce the brightness of flashes (from normal brightness down to turning it off completely) from hitting notes, that would be much appreciated. Other comments are as follows: • Some of the songs could really use a few more charts (like Flashbacklog, for instance, with its endless 32nd notes). • The last time I played TRUE END on Normal (rated a 6), I went like, "What the heck is this!?" because it was as if I was playing an Ultra chart or even a Master chart! (How about swiping a stream of sixteenth notes left and right while holding down a hold note at 190 BPM?) It makes me wonder if two charts accidentally got swapped on this song, and I wasn't playing the actual Normal chart. • Also, when I was playing on Very Medium several months ago, if more than two notes came up at the same time, I couldn't just hit two of the notes and have the others ALSO be hit without having to touch them – I'd have to swipe like a maniac so all the notes could be hit! • I hope something similar like this doesn't happen with Very Easy, and if it does, that'd be WAY worse! Hoping the note lag problem gets solved – that'd be good enough for this game to get 5 stars! ☺️
