Yeah, it's my plan to implement daily levels, as well as weekly levels.
I was thinking of making weekly levels be very big (like 12x12) where I don't know what the par is myself, and have it be a challenge to see who in the community can figure out a way to get the lowest number of moves.
And daily levels would probably be more similar to the regular levels.
Thanks for replying. Since you're considering bigger levels, maybe three daily levels: easy / medium / hard.
On my games I usually go with five levels [1], in different tabs that can be solved concurrently, from very easy to very hard. People seem to enjoy the progression.
