a nice little virtual way to have a goal, solve a set of problems, or enter another world. focusing in can dissipate bad thoughts and make your mind a clean slate by the end of a session. bonus points for difficult games bc they tend to really make the day fly by
games i like for these kinda days:
Moving Out - a game where you organize the contents of the main character's boxes into various houses she moves into throughout her life. very relaxing and pretty addicting
Cuphead - very difficult game but if you're looking to make a day pass, it's easy to spend hours on it throwing yourself at its bosses over and over
Celeste - another game that's as rewarding as it is difficult. could replay these levels forever probably
Pikmin 4 (or any of em) - another cozy option that gives you a great sense of accomplishment and lots of little goodies to collect
Peggle - a classic
Minecraft - another time-killing classic, especially if you plan out a nice big project
