that issue was fixed, but different issue seems to be occurring!
I'm sorry, but an uncaught exception occurred.
While loading <'Image' u'00-renpythm/images\\up.png'>:
File "game/script.rpy", line 52, in script
call screen rhythm_game(audio_path, beatmap_path, beatmap_stride=2)
File "renpy/common/000statements.rpy", line 570, in execute_call_screen
store._return = renpy.call_screen(name, *args, **kwargs)
File "game/00-renpythm/rhythm_game_displayable.rpy", line 207, in render
render.place(note_drawable, x=note_xoffset, y=y_offset)
Exception: Backslash in filename, use '/' instead: u'00-renpythm/images\\up.png'
also copy-pasting my comment from above: i noticed that the download comes with copyrighted music - i suggest switching to music you have permission to use! (as it is now i don't feel comfortable recommending this engine to other people since it seems to just have music downloaded from youtube included in the files.)
