Dave the Diver. I had put down gaming because of tiredness and this game was such an unexpected joy of exploration and cute story for me. Easy to pick up and do a quick dive, decent progression based on a mix of skill and leveling up your character, and the writing was excellent. First game I 100% in forever and it was while playing it 30 minutes at a time.

Is there any chance the buzzing is actually from what you have the PSU plugged into? I think ive had a surge protector that have a buzzing without anything drawing power that went away once something was consuming power.
