really nice level of polish, especially in the menu selection / background. I'm a big fan of sudoku games so this was right along my alley. Would be nice to add some objectives for the number of steps to solve dokus by for each level of difficulty. The music was a bit short and ended up being repetitive, but overall it didn't take away from the gameplay. I also love the PICO8 vibe!
I played every bit of difficulty and the hardest mode a few times, with 30 as my high score.
Great job overall!
