Made a Regex Daily Puzzles Website

It's just a daily puzzle website (plus the ability to go back up to a week for old puzzles) but for regex. I think I've worked out most of the kinks but if you find any issues let me know. You don't need to make an account to play, I just added that for score tracking if you want. There's a how to play button at the top but if the instructions are confusing, let me know! I'm open to any kind of feedback! I don't think the puzzles are too hard (even the "hard" ones) so it should be good practice for some basic regex.
