Hello! I would like to say that I find the challenge log a compelling way to try different things in game as well as repeating content, but it seems to me that the way the game notifies you of a completed objective is rather bland. I would think that using a type of sound effect and slightly more noticeable pop-up notification, similar to the Playstation or Xbox consoles for example, might be an effective way to add an extra "pop" to let the player know they just did something meaningful.

Thanks for reading!
