Firstly thanks heaps for playing on stream. Time zone issues didn't allow me to watch live but I looked at the replay.. it's always great to see people play your games on stream! :)
Cheers for the comments about the look and mechanics, happy that it worked well.
You make good points about the puzzles, certainly the [7]'s puzzles don't make the symmetry mechanic obvious enough. FWIW having you and some other people play it on stream (as well as comments) has really solidified that the intro puzzles are so important in terms of difficulty curve -- even more so that mid- and late-game. I'll fix them for this game, and be better "for the run" for the next jam, hehe.
Regarding the extra colours. Every puzzle *should* have the number of colours equal to the maximum number of colours with which it can be solved. Some puzzles can be solved with less, and some puzzles have extra colours for other reasons (later in the game, no spoilers). But yes, solving with the minimum number of colours is always a valid approach! You did.. however.. stumble on the one puzzle I believe which has an extra colour for no reason -- again sorry for this, definitely was confusing to find it at that time -- another thing for me to fix post jam. :)
If you decide to play again, do let me know if the tutorial helps? In hindsight, shouldn't have told people not to read it, and should have put it in game.
Again, thanks for playing. Your stream was entertaining as well!! Enjoyed watching the other games get played. 👍
