Impressive that you made 24 whole games - even though they’re small, that’s a lot of coding! The Picotron style looks great as always. I think overall you did a good job making games that are intuitive enough to be doable on your first try with some quick thinking, but not trivial. My best score is 18 in one run. :)
One suggestion would be to make the transition between games be a manual input instead of automatically triggering on a timer. That way if the player wants to take a break or pause and inspect their progress, or if they want to get to the next level right away without waiting for a transition (e.g. on repeat plays), they can.
