This is really well made! As someone who has built daily puzzle games (ex. sidewords.ca, kickoffleague.com, and just today fivefold.ca), I appreciate the effort it takes to make something that polished! It plays really well on mobile, which is tricky, especially when you’ve got a grid as big as yours.
Hah well one tip would be do NOT make a complex framing/structure for your daily puzzle game like we did with Kickoff League. It was a fun experiment but it mostly just confused people.
A more meta tip is if you make multiple games, try to have some genre or theme overlap so you can build a community among players of your games. I wish I had done this more with my more successful games (which are mobile games, not web games, but the same idea applies).
