Skins are written in the lua syntax and can be found in ./GameData/Skins/.
Currently the game comes bundled with 7 different skins:

• Default
• focusjam (Good for o2jam players)
• ftb2d (Feel the Beats adaptation)
• midi-note (good for Stepmania players)
• simple (IIDX/BMS-like skin)
• vicinity (Good for o2jam players)
• wafles4 (also good for Stepmania players)

To set your skin of choice, open config.ini and find the line Skin = , which should be placed under the [Global] tag.
You want to set Skin = foldername, where "foldername" is the exact name of the folder of the skin you want to use.
If a skin does not support a certain amount of keys, it will revert back to Default.
Also be aware that not all skins support "upscroll". If a skin does not support upscroll, it will look very broken. (It will NOT revert back to Default).
Here is a preview of each bundled skin's play screen.

The most flexible and supported skin. Supports any amount of keys, as well as upscroll.

If you want notes scrolling upwards, make sure to tick of "Upscroll" in the song select screen.
