Subtle but direct sound indicating that the player character has reached a new level.
The one sound in this pack (3.33s) consists of various drums that grab attention without interrupting regular gameplay and let the player know what happened.
The sound could be also be used for other sounds indicating progression in a quest or some other significant event happening.
It was created to capture a feeling similar to the level up sounds in current epic 3D role-playing games, rather than retro cute or low-fi arcade games.
