The only advice I could give, is maybe some sort of mode for beginners where if you have a tile in the correct spot, it locks in. Or maybe if that's a bit too easy, maybe after a certain number of correct tiles, those lock in where ever they may be on the board. Not sure what the number would be... half? Or maybe you get to choose to increase difficulty slowly but surely as you play boards, similar to the other sliders in the game. Otherwise it was neat.
Yeah, I did consider locking correct tiles at some point but thought it would stray too far from the original idea, but I guess it doesn't really make sense to restrict myself to that since the goal is to give more options.
I'll probably implement something like that when I get back into it, it would pair well with a "difficulty presets" setting (preset layouts) that I wanted to make.
Thanks for the feedback!
