just to point it out, the demo crashed with an error:
############################################################################################ ERROR in action number 1 of Alarm Event for alarm 1 for object obj_player: audio_get_name argument 1 incorrect type (undefined) expecting a Number (YYGI32) at gml_Script_change_bgm ############################################################################################ gml_Script_change_bgm (line -1) gml_Script_set_area gml_Object_obj_player_Alarm_1
no idea what it means, as there is another error, but it needs to be checked
in the javscript console:
Exception thrown: See Javascript Console.
it looks good for the point of view.
