Hi~Hi ( ˙▿˙ )ノ
Which VN Engine are you using? |･ω･) Maybe can you tell me where the problem occurred? ((Like where an error message appeared or are you having trouble with the code(?)
If you purchased this GUI Pack - Normally, if you unzip the (GUI Pack 007) compressed file and put the entire folder in the place where you store other Renpy projects, you can open it directly with Renpy (Sry (>_<) I am not really familiar with other engines)
If you download the free version - After unzip the compressed file, you will see all the pictures I used to make this GUI - The pictures inside can be used in any project / any other engines freely
