Charming! A very solid and polished experience, nicely done. Art design was lovely. Audio sounds were fine, but for a longer game like Sudoku, you really need either a longer track or multiple tracks. Gets old after awhile.

I actually really liked this! 

I am going to presume you did all the music and SFX for this game. The music was very well written and mixed! But it felt too busy for a sudoku game; I found myself too distracted by the music to focus on the numbers sometimes! There was a section in the middle that was more subdued; I wish that could have been the music the whole time.

The squeaky sound effect of the witch is too loud; I don't mind it, but it hurt my ears in my headphones. Art is adorkable. Puzzles are good, ended up doing one of the easy ones. 

Nice art! And quite polished. Interesting choice to make a Sudoku game. The connection to Halloween seems purely aesthetic, it would have been nice to have it integrated into the gameplay somehow.
