What does not
Almost nothing. Just a low FPS. And Long notes is a bit buggy (After a few seconds, It presses rapidly rather than holding. If you know what I mean).
What was not tested
Buying item from in game itemshop
Downloading Music in game
Go to My Room, Music Shop, and Itemshop
I didn't install from my Installer, I use Inno Setup for the installer :D
By the way, The Gameplay runs smoothly without lag. Just a buggy long notes makes me hard to Full Combo a song.
And, the taskbar (top and bottom) won't hide when the game is running, thus i can't see the bottom and top side of the game
I would rate this gold or even platinum If no low FPS in Lobby and rooms.
