I'm also not great at rhythm games but wanted to challenge myself making one, so I can agree it feels wonky. I'm not sure on the 16:10 but it could be the UI scaling weirdly with the anchoring UE4 does. I initially wanted to try scaling the entire game getting incrementally up to 2x speed but I didn't get around to that as I'd have to scale the music to the speed as well. I could set the global speedup time of the game but it didn't affect the music haha. Thanks for playing!
